GM NOTE: It made a fantastically creepy villain.
I am going to list just the info of the Blood Beast here
This is a summoned tectonic entity and it is constrained into the blood released by the spellcaster, forming a being known simply as a Blood Beast. The blood beast stands about seven feet tall and appears as a featureless humanoid comprised solely of blood that is constantly flowing and shifting.
There is a 20% chance that the entity will not return to its own dimension and will no longer obey the spell caster who summoned it. If this happens, it will remain in the caster’s dimension wreaking havoc and killing for the shear pleasure of it
