Crosell, known to those who haven't gained his trust as The Marquis, is the largest Air Dragon on all of Elicoor II. Not only is he the biggest, but he is one of the few who is fully sentient, and looks down on Humans, especially those who don't realise that dragons can also be sentient. He is fought as a boss in Star Ocean: Till the End of Time.
The party ventures into the Urssa Lava Caves in search of Crosell, since they need an Air Dragon large enough to carry the Thunder Arrow. When they encounter Crosel, the party is amazed at his size, and Cliff is taken aback when the Air Dragon talks. Crosell is angered at his arrogance, and is not amused when Fayt asks him if he would carry the Thunder Arrow. Crosell then engages the party in battle, claiming that he will only serve those who can beat him. While the party does beat him, he immediatly fights them again, this time using all his power. He is once again defeated, and even though he doesn't like serving humans, he cannot just go back on his word.
Crosell takes the party back to Aquios, where he is fitted with the Thunder Arrow. The party then begin their assault on the Vendeeni fleet over Aquios, with Crosell leading the fleet. After the battle is over, Crosell returns to the Lava Caves to rest. If Albel Nox was not taken upon Fayt's first trip to Moonbase, he'll be in Crosell's cave with him.
