A demon of utter chaos and death. The ultimate weapon of the infernals!
The Reaper is a demon of unsurpassed power and destruction. While the ability to summon such a creature is within Xin's ability the power to control it is not. This creature would only be unleashed as a true doomsday weapon upon whatever unfortunate sorry creatures that Xin hated enough to risk the consequences of daring to summon such an infernal horror. (Think Cthulhu, only pissed off at being summoned and on steroids…)
