The niter on the walls of the basement of 567 Elkhurst forms glyphs. For those who can read them, the glyphs tell an amazing tale of the last children of angels and the gifts given to them from their rather absent parents and how they had to face the evil goblins. Definitely worth the effort of learning a dead language and spending time in a dark, dank basement. Oh, you did know that goblins love the dark right?
This was something you needed to know.
