The klagen geist is a truly pitiable creature. Undead creatures exist for a number of reasons; as a curse, as penance for a sin, to fulfill an unfinished duty, as the servants of a necromancer. When an undead is killed the sprit animating it finally is allowed to move on to wherever its final resting place is, for good or ill. The klagen geist is that extremely rare type of undead, one that should have been released on its way but it can not.
The klagen geist is caught between the spirit world and the mortal one. As such, parts of its body have moved on and others have not. At first glance it looks like floating bits of flesh and bone advancing, but upon closer inspection it is revealed that the body form is simply missing large pieces.
