NEW FRIENDS AND NEW ENEMIES
Pgs 101/134 The Bloodhunter. It's squat, dwarflike and the colour of an Earthworm, with a bulbous head and tangled tubes. It's hairless, roughly humanoid, with fingers that taper to bony points, a head that's barely more than a fleshy stump on round shoulders, a cluster of eyes and organs that look like dead snakes.
Pg 200/261 The Dark. An entity from before the Big Bang, its physical body was burnt, but its mind lived on and was able to reconstitute itself using the blood of humans. It has tentacles of shadow and a cavernous maw, but then settles into a new shape: a parody of the Doctor, with small, sinuous things crawling all over its flesh.
