Seventh Founder
From Tardis Wiki, the free Doctor Who reference
The countercultural Nechronomancers worshipped an incomprehensible "Seventh Founder",which they referred to as "the other", who was nameless, genderless, and historyless. (PROSE: And To Dust We Shall Return, PROSE: [The Book of the War (novel)|The Book of the War]]) It was unclear whether this "other" was the same as The Other that was part of the Triumvirate, although their labelling as "seventh" (contrasted against the usual count of six) implies a separate identity to the member of the Triumvirate
