Seer

From Tardis Wiki, the free Doctor Who reference

Seers were important members of the society that developed on the "P7E planet". They reported only to the Oracle, and held authority over the Guards, who in turn were in charge of the "Trogs". Like all beings on the "P7E planet" they were in some way descended from Minyans, though were far removed from the Trogs and Guards, in terms of appearance.

Two Seers, Ankh and Lakh, interrogated Herrick and devised a plan to blow up the R1C by disguising bombs as what appeared to be the Minyan race banks. Later, when the "P7E planet" was destroyed, all Seers apparently perished along with the planet. (TV: Underworld)
