Returning to lore bits! Upped the detail on the background a bit more for this one.

Lore bit:
A great Delthulian snack is the crystals of the earth. To any other race, eating crystallized minerals may seem like an awful (and painful) experience, but to Delthulians, they’re a tasty morsel. Unharmed from the consumption, they enjoy their crunchy treats as a midday snack, or a desert.
..yes, that means you might catch Zen eating a few rocks like an actual maniac. Being half Delthulian, he has a guilty pleasure of crunching on crystals, describing them as “sweet and embrittled.” His particular favorite crystal to consume are the Ashca crystals which form commonly on the western side of the Nufk highlands, they apparently have a cherry taste… to only him.
