Fellblade

The Nameless One, trapped by the Elder Sign within Crypt, has found
a means around its imprisonment.  It has spread its horrible influence
by crafting itself into Fellblades and grafting its life essence to 
Gifted Ones, who arguably are choosing to sacrifice their own 
souls to the Nameless One rather than the Nameless One 
possessing them. Thus it uses these "feelers" to gain in power when 
it will be able to finally free itself. Thee proposed number of
total souls is 666,666,666,666,666,666. For more information
