It's probably Garland. Some people say fighter, and some say Garland. The guy does wear a purplish armor, and a large horned helmet - very Garlandish. He also carries a crystal on him (the necklace). This is the thing that makes most people say fighter, since he's a swordsman with a crystal. I say it could go either way. The outfit is very similar to Garland's, but on the other hand, Amano's art is often very stylized, and he could be a CG of one of Amano's interpretations of "Knight". A swordsman bearing a crystal, fighting a red dragon is very Light Warriorish. Anyhow, I'd have no trouble believing either side. In the mean time, I have a vested interest in maintaining that the guy in the CG is Garland, for obvious reasons.
