Silver was born a human, but after faking their death and fleeing to a frontier moon to forcefully abdicate their position as heir to a megacorp, sets up shop pursuing their passion, making custom gene-mods. Their own form is that of an anthro yinglet featuring some pretty major differences from the baseline form.
They have a hyperfixation on 21st century species like chakats, skeksis, sergals, yinglets, etc, and primarily provide mods based on such things. When not working, they enjoy hikes around the snowy moon, smoking fat blunts, and watching old cartoons and anime from all centuries.
