Kasch

Kasch is a creepy artisan encountered during the Dwarf Commoner Origin.

Involvement
Kasch tries to solicit for the Warden to sell his/her teeth and hair, which he crafts into "replacements" for nobles that lost theirs. Dialogue with him can illustrate the rights of the casteless -- or rather, the lack of them -- and Leske will rein the Warden in if he/she threatens him with violence.
