Dieselpunk style is a major component of the NecroMech game world. So for characters with a Tooth Graft from Othersider UX-170 (“Vampire”) that need to hide their deformity, one they are eagerly willing to endure to gain Necrovasculation, Rupture, and Hateful Harvest, a mask is in order. Perhaps something like this that the (cos)player could also wear to the game table!
