The Grey Seers of the Priesthood are the chosen grey-furred emissaries of the Great Horned Rat, unholy prophets of ruin and destruction capable of channeling eldritch energies in destructive ways, levelling armies with lightning, or summoning ravening swarms of rats, all for the sake of furthering the Skaven cause and bring about the Great Ascendancy of their foul deity. As chief agents for the Horned Rat and the Priesthood dedicated to his worship, Grey Seers wield tremendous influence amongst the clans, and only a fool would ignore their council and to inquire the wrath of the Horned Rat's chosen.
