its way too late but why not. who should I play from your canons

Flame Reaver

assuming that FR is an entity that has free will and sapience, and ideally also a Phainon somehow

hmmmmm I feel like. if you played geno from smrpg. you'd be a good geno. nonbinary star thing sent from the cosmos to help fix things, possessed a doll, which he is still getting used to piloting

man. flame reaver..... yeah if flame reaver actually had free will and sapience, i can see the vision here

geno...............i need to play smrpg. watch it. pulls it slightly higher on list
