The short form for tomestones is tomes not tombs

[Cynric]

Tome and tomb are both pronounced the same way. Tombstone is a word outside of this game, tomestone is not (as someone earlier pointed out). I can easily see why people go with tomb if not reading carefully (our mind does kind of "autocorrect for us a lot). Really not that big of a deal to me.

tome t oh m

tomb t oo mb

Im sorry what?
