Keaver
From Tardis Wiki, the free Doctor Who reference
Keaver was a resident of K'anpo Rimpoche's meditation centre. He, Barnes, Moss and Land worked with Lupton to summon the Eight Legs to Earth. He was taken over by them, but was freed when the Great One died. (TV: Planet of the Spiders)
Behind the scenes
In the novelisation by Terrance Dicks, it is stated that Keaver, Land, Barnes and Moss were hospitalised with nervous breakdowns following events at the meditation centre. This was not derived from any information given in the televised version.
