The Sacrifice the Eyeless Face Demands is a book and quest item in The Forgotten Sanctum.
The yellowing pages of this thick, locked tome are written in a dark green ink. Within it you find mad poems, nonsensical formulae, and impossible sketches. On one page, you find the following scribed in blood:
The titan opens only to those who have undergone the mystery of the Trephine.
Use of the Trephine requires understanding how the Trephine is used.
This mystery cannot be taught - only experienced.
A memory of a thing is not the thing itself.
A memory of a thing is a thing itself.
The Trephine demands the understanding of its use in sacrifice.
Sacrifice the understanding you seek.
