In his mind space, Eldrian found himself at the valley where Two had constructed the library. The center of his soul. In haste, he confined the foreign substance and kicked it out of the world he had created. Confining it to the outer edges of his soul. Using the lich's absorbed lifeforce to form a prison.
The glowing of the foreign substance was distorted by the prison, but still clearly visible at the edge of Eldrian's mind space. Surrounded by endless darkness, it rested. Seemingly at peace.
"I'm afraid I can't gleam much information from it. When attempting, I can extract the contract details. But nothing else." Two commented once Eldrian had finished locking it up.
