Fragmenttale

non-human characters that are part of my undertale au, fragmenttale!

some notes on the fragments in particular, since ash's main bio doesn't go too into detail on them -
* basic premise is that when gaster split apart, he was split into ash, and then four other fragments that became scattered across different timelines
* these fragments are all facets of gaster in some way, and are all smaller than ash. ash is the "heart" of gaster, and the largest fragment
* in another timeline of this au, after discovering reason in his own timeline, he would fall into the core with reason, go to another timeline, find a soul fragment there, they would gain a form, then try to find the core in That timeline, rinse and repeat
* then when all the fragments reunite in one room, there are two ways the timeline diverges
     * in one timeline, all the fragments (except ash) reunite into an incomplete form of gaster. over time, ash's own soul starts to deteriorate, as he's still only a fragment, and he either a) fuses back with gaster to save himself and resides in gaster's subconsciousness as his own separate entity, but still part of gaster or b) eventually dies, and is able to be resurrected by gaster as a skeleton, with a new monster soul that's directly connected to gaster's own magic
     * in another timeline i like to imagine somehow they're able to remake gaster, but all the siblings are Also able to coexist along with ink and gaster and its just one big happy skeleton family because i love these idiots too much to put them through more pain

* all of them, sans amygdala, are capable of communicating through sign language
