Papers from the Fraternity of the Empty Moon

(written in a strange language, a variant of Abyssal)

• Pages and pages of calendars with notes and calculations on them, tracking phases of the moon. Most of these seem to be newer, written in the same handwriting.
• There is also what looks like an older scroll, written in the same tongue, loosely translated as:

  When the sixth moon rises in the betrayer sky,
  When the deepest echo of madness is nigh,
  In the ancient cave of the Mad One’s soul.
  Thirteen brethren, thirteen prayers,
  Thirteen cold iron spears prepared,
  Will bring forth the howl of empty despair.
  And Jinnik’s curse will claim the land.

• There are several pages of notes. You can see a few diagrams, one that seems to shown thirteen poles or spears, point down, arranged in a circle, with the details on the spears revealing “Mad One, come to us, let Jinnik’s howl be heard!”. These spears are identical to those found in the lair.
• There is a long discussion of the “ancient cave of the Mad One’s soul” and its connection to Pandemonium, linking it to the cave to the north.
• There is what seems to be someone’s notes to themselves, “We must find a way past the Dunmari’s maze, and we must find a way to get to the Dunmari city without attracting attention. Maybe the old witch can help, if I can find something to trade worthy of her.”
