Oh god

why D:

Why not?

Though seriously probably was researching if we could create a body part item. Funny thing - DF heart is useless so you can live without it.

Ah ok. 'cause the stuff about placing and "easily remove" implied that there was some sort of use that this just makes easier

Thought it might be for: https://github.com/warmist/df-mini-mods/blob/master/gloom/idea.txt df mod idea. From the "research what spells and stuff would be possible" part of development.
