Sunyata

From Tardis Wiki, the free Doctor Who reference

Sunyata was an entity that resided within the Void. It could best be described as an empty shell, and would consume everything in its path. If Sunyata was to enter a universe, it would shred planets and matter to fill the void of its being.

According to some accounts, the Great Intelligence was an aspect of Sunyata that entered the universe.

In January 1970, James Gore gained access to the Void by tapping into Owain Vine and Edward Travers' connection to the Great Intelligence. This act unleashed Sunyata on the universe, and it briefly occupied the body of Gore. Sunyata was stopped when Padmasambhava unintentionally revealed his true self to Owain in the astral plane: a being of pure light. (PROSE: Night of the Intelligence)
