Ok, it kind of looks like I've been isekai'd here. Either that or I did way more drugs than planned at LessOnline. Should probably work out if I've gotten any magic powers in this isekai/hallucination. *concentrates*

You notice a power growing in you, which you didn't feel a moment ago. It seems like the power is coming into being progressively - it didn't exist the moment you came into the world. It is one of the following:
Light, Shadow, Flesh, Blood, Bone, Glass, Animals, Ice, Water, Fire, Earth, Metal, Wood, Wind, Electricity

Looking at the five fancy people around you, you see:

A rotund woman with unusually smooth, almost waxy skin that seems to ripple slightly when she moves, her fingers oddly plump and her smile revealing teeth that appear too perfectly formed.

A gaunt man whose angular frame seems to consist of sharp edges and pronounced joints, his prominent cheekbones and long fingers giving him an almost skeletal appearance despite being very much alive. He wears a bandolier filled with what appear to be animal bones.

A pale, intense-looking woman with startlingly red lips and fingernails, whose dark eyes seem to have an unusual reddish tint in certain lighting, wearing deep crimson robes.

An elderly man whose face bears an intricate patchwork of different skin tones and textures, as if they've spent years in various climates, with hands that show calluses, scars, and smooth patches in unusual patterns.

A striking woman whose impossibly long, lustrous hair seems to move independently of any breeze, cascading in waves of multiple colors that shift subtly.

This is shaping up to be a nice isekai/hallucination. I don't think anyone actually said this, but I think there should exist some sort of principle that flesh is the best answer in "what magic domain are you getting?", so I'll try to think fleshy thoughts for now. 

I should probably also try to talk to these people before too long, but phenomenal cosmic power comes first of course.
