Gravestones

Gravestones are found all throughout Rythulia. They are generally used to mark places where a Rythulian died, though there are some that serve other purposes, and may not technically be gravestones at all.

Murals
Nearly-all Murals are activated by two gravestone-shaped markers at either end. These markers could be the least likely to be actual gravestones - or at least, it seems unlikely that they would be marking resting places.
