Dave's story is a sad one.
His creature, an elf, was one of the elves who was taught photosynthesis. And that poor elf always wanted a pet photon. And knowing photosynthesis, he tried it. It was then the elf created it's first mutant. A 1|1 cocktrice with ability "bioluminescence". After that, the elf tried to keep things on the down low. Sticking to the easier creatures to make, and killing all his failures, he stayed under the radar. But when the elf was asked to make a jade dragon in front of the mutant containment committee, Dave was born.
The entire journey to the entropic lands, Dave was mistreated. He couldn't speak, his intelligence equaled that of a baby, and the elf blamed Dave for his own failures. And well, one day Dave hit back, and hard. It didn't do to much damage, but it did enough for the Maxwell's Demons to get him. Dave had to teach himself from then on, eventually learning to speak common from the lycanthropes.
Dave has good relations with the entropics, the aetherians, the vampires, but poor relations with the elves.
