Morgan Black

• "Get some soldiers to protect those settlers. If they die, we die."
• "Why do you call me that? I'm Scottish.
• "Good work."
• "Excellent work, men!"
• "So this is what the Ottomans really wanted on Malta."
• "What, across the Ocean Sea?"
• "We are Knights of St. John. We do not surrender!"
• "Our ship is badly damaged. Start a colony on this island and wait for more ships to arrive from Malta."
• "Sahin has beaten us here, but we'll worry about him later. We need to get our colony started."
• "Speaking of hurricanes."
• "So, Sahin, it seems your Spanish friends have left you here to die."
• "What are you saying? Alain has given his life to my knighthood. He's no member of this Circle."
• "Ram the Fountain with a fire ship!"
• "Our base is over-run. All is lost."
• "Amelia Black. The girl who owns Falcon Company. Is it true your grandmother was a Mohawk?"
• "This land belongs to you now. You and folks like you."
• "You broke the Circle, and in just one lifetime, too."
• "Don't miss your train."

Alain Magnan

• "Why is the signal fire lit? And why am I here, Morgan? I ordered you to defend the fort."
• "The Falcon can't stand up to my heavy cavalry. Lead on, Morgan, and destroy those cannon."
• "Once the Ottoman weapon caches are destroyed, they will be forced to leave Malta."
• "Morgan, why is that savage still alive?"
• "You and your band of misfits will be wiped from the New World, Morgan!"
• "No! Morgan seeks to destroy the Fountain! Stop him!"

Sahin "the Falcon"

• "It is already broken, Morgan! Will you break with it?"
• "We do not have to fight, Frenk. Do you never question foolish orders?"
• "I have no quarrel with you, conquistador. All I wanted was a look at an old map."
• "If you kill me, there will be no one to stop the Circle of Ossus."
• "Do you see it now, Frenk? You have been tricked."
• "Open your eyes! The Circle wants the lake because they think it is the Fountain of Youth! All I have been trying to do is keep it out of the hands of the Circle! And Alain Magnan!"
• "I am Ottoman. I have more than you could possibly ever use."(Talking about black powder)
• "Destroy it. It is the only way. You cannot leave the Fountain of Youth in the hands of such men."

Elisabet Ramsey

• "Knights? How quaint."
• "Morgan Black. So the New World hasn't killed you off yet. What's this I hear about Florida?"
• "Wait just a minute, old man!"
• "My ship! I'd better be paid well for this, Morgan!"
• "Morgan, he makes sense. Alain left you to fight the Spanish while he raced ahead to the lake. He's been using you."
• "My fire ship was destroyed!"
• "Another fire ship has arrived."

Francisco Juan Delgado de Leon

• "So, we have captured not only Aztecs, but a Turk as well. What is an Ottoman doing in the New World?"
• "Bah! The Circle is nothing more than a legend! No match for powder and steel!"
• "Stop them! They're taking the king's gold!"
• "They have stolen one of my treasure ships! That treasure was meant for Spain."

John Black

• "And your eyes were better once. Your arrow missed the mark. My shot was the one that took him down."
• "Only a few more miles to Brunswick, boys. You've marched long and hard, and you all deserve a hot meal."
• "Stuart may not be the commander my grandfather Morgan was, but if he thinks the colony is threatened, I believe him."
• "I don't know, but they're not peaceful anymore! Prepare the defences! We need every colonist that can hold a musket on these walls."
• "More colonists - get them into the colony! Hurry!"
• "You colonists will have to fight alongside us. Give them weapons. They're militia now!"
• "Stuart, you stay here with the other women."
• "Six of you stay here to protect the wounded. The rest, with us."
• "Ambush!"
• "Those are British riflemen! Why are they attacking their own colony?"
• "Ride back and tell Stuart that we'll do what we can! We've got our own problems here!"
• "Hold on, Nonahkee. We're coming!"
• "Warwick doesn't need to look for me. I'll go to him."
• "Have you told your brother about us yet?"
• "The French cannot be trusted."
• "Who's asking?"
• "They're just madmen chasing after an old legend. They believe my grandfather Morgan knew the location of the Fountain of Youth."
• "Nonahkee goes home. This will end badly, and I don't want her to see it."
• "You already know about us, don't you?"
• "They may know where Warwick is. Come on."
• "This beast is enormous!"
• "We have all the settlers we'll get. For resources, we'll need to steal some of the supply wagons being escorted into Warwick's fort."
• "We only have a short amount of time before Warwick's fort is too well-defended to destroy."
• "I'm going to bring the mountain down."
• "Warwick!"
• "You shouldn't have taken Stuart!"
• "There is no secret."

Kanyenke

• "Too slow, John Black. You were faster once."
• "This is a waste of time. Your uncle sees a shadow in the forest and cries for help."
• "Why would the Cherokee attack? Brunswick is far from their lands."
• "We've found the Cherokee war camps."
• "Something feels wrong here, John."
• "That explains the Cherokee cannon. They have allied with the British!"
• "Then my tribe and my sister may also be in danger. We must get back to New England."
• "My people cannot hold off the British for long."
• "We were delayed."
• "It is your uncle. I will put him to rest where the others fell."
• "Be careful. I know nothing of the people of this land."
• "The Great White Buffalo is sacred. We must rescue it and lead it back to the Lakota village near where we first arrived."
• "Amelia, stop! It's a trap! He leads the Circle!"
• "Can you help us?"
• "The Circle is all too real. Your grandfather John learned that before he died."
• "Beaumont has allied with this Seminole tribe. If we destroy his trading post, we will be free to ally with them ourselves."
• "The local Seminoles have a legend, but their chief can explain better than I can."
• "Stop that scout! If he reaches the Boneguard army, they will be able to move forward."
• "In my experience, the American government's promises are...less than reliable."
• "Perhaps the reports of the Mohawk and the Seneca allying with the British have been exaggerated."
• "Kill now! Talk later!"
• "Each time a travois passes our trading post, a new villager will join us."

Stuart Black

• "John, thank God you're here!"
• "Grab rifles and defend the walls!"
• "Cannon? How did the Cherokee get cannon!?"
• "Yes, I think my skills are best put to use here."
• "Oh dear!"

Warwick

• "Find a member of the Black family and kill the rest."
• "It is time we discussed the location of the Fountain..."
• "Take Black's uncle to our western fort. He will tell me where the Fountain of Youth is before he dies."
• "No! This cannot be! My stronghold is crumbling!"
• "You're delaying the inevitable. The New World belongs to the Circle of Ossus now."
• "You're right. It seems you're the keeper of the family's secret."
• "Perhaps. Are you made of stuff sterner than your uncle? I so love a challenge."
• "Fools! The powder!"

Nonahkee

• "Brother, what took you so long?"
• "The new British governor, Warwick. He knows you, John."
• "Later, when it is a quieter time, he will accept it. But not now."
• "I'm free. Thank you all."

George Washington

• "Are you John Black?"
• "The colonial army has survived to fight another day."
• "Here is another artillery piece, Nathaniel."

Amelia Black

• "Sorry, old man, but I don't have time to chat."
• "Allying with the Indians in this region will greatly help us get this railroad through."
• "Do I know you, friend?"
• "Good work."
• "I've got to finish the railroad if I'm going to get paid."
• "Bring that wagon to Kanyenke. He can use the food to recruit help."
• "It looks like Beaumont has fled, but look at this."
• "That old story again? Did you forget what year this is?"
• "I don't see any Fountain of Youth, but the area is littered with doubloons from that old Spanish treasure fleet."
• "Beaumont will pay for this."
• "This place. Is it real?"
• "Falcon Company wasn't the first, but we'll still get a piece of the pie."
• "We managed to find some new...investors, in Florida and Cuba."
• "I'd stay and chat, old timer, but the train's coming."
• "What did you say?"

Major Cooper

• "Get everyone into the fort!"
• "Thank the Indian. He tracked you for many miles across rough ground."
• "This swamp was the Lake of the Moon?"
• "We've flattened one of the outposts. Two to go."
• "Surrender, or you'll face justice right here!"

Pierre Beaumont

• "She can fight, this pretty one."
• "Leaving so soon?"
• "Not far, see? In the cave, there."
• "Too slow, cheri!"
• "Be sure he knows nothing. Take his fingers, then his toes, one at a time."

Simon Bolivar

• "I know this place. You'll never get past the Spanish. But, together we can organise an assault. Help us rid ourselves of the Spanish and I will help you find your Frenchman."
• "I see you beat me to this village. Excellent work, my friend."
• "Attack the fort! A la carga, mis valientes!"

Nathaniel Black

• "Hold the line!"
• "You were saying, uncle?"
• "Yorktown has been heavily fortified."

Colonel Sven Kuechler

• "They have allowed some of those villagers to be freed. I should have stationed more of my mercenaries at that pen."
• "We will have only one patrol tonight. Enjoy your evening, men."
• "No, I will not be defeated by you! No!"

Billy Holme

• "You the Falcon Company man, Chayton Black?"
• "Nice work tracking down Crazy Horse, kid. Just like the old days, huh?"
• "I've been patient, kid, but I'm getting tired of your attitude."
• "I thought I taught you better than this, kid."

Other characters

• Crossbowman: "Morgan, the Ottomans are flanking to attack the settlers on the hill!"
