You don't play as the Reptite time-travelers, they're actually enemies, but not "evil" ones (they're like the heroes of the Reptite world, so they're opposed to our human heroes).
I'll see what I can do with Serran's body. I intended him to look like a buffed-up Mystic in an armor too big for him, because of the description:
"Kasmir - Kasmir is a forerunner to the Heckran in CT, a sort of miscreant that likes stirring trouble and tries to revive Mystic hostilities. He's relatively unpopular until a tumultuous event causes many to find faith in his views."
(The name Kasmir was changed to Serran). I imagine him having borrowed a badass armor and sword but not knowing how to use them^^ But yeah I'll see if I can correct the sprite a little.
