Perhaps create a skill to be able to move a corpse across rooms. Naturally, the skill would come with a huge lag, and possiblility of failure based on factors such as size, strength, dexterity and maybe even a movement cost. Allow for bloody tracks or impressions showing the path a corpse has been dragged through, and perhaps have these disappear only when the corpse itself purges. From a game balance perspective, the skill can be used to avoid friends of the deceased, confuse the deceased, allow for sorting through gear easily, and/or to set traps (all possibly exploitable). From a roleplaying perspective, the corpse can be brought to a signifcant room such as a graveyard or similar burial ground or a warning such as outside of a Cabal or city.

The skill can be class-specific such as for rangers, paladins, necromancers, shapeshifters, transmuters, or assassins, or race-specific as an inherent skill for felar (think of great cats moving a carcass to a safe place to consume), or even Cabal-specific for Sylvans, Maran (Acolytes might view the act as too bloody) or the Black Sect in Empire.

Side effects can be similar to the cause of death of the corpse, for example a plague for diseased corpses, immolation for charred corpses, etc. Muscle straining, becoming trapped under the corpse, or destroying the corpse come to mind.

To prevent possible exploitation perhaps create limits on where corpses can be dragged, for example never within a Cabal, on or in water, in the air, and a substantial lag to prevent moving completely a few areas away. Another possible exploit would be to drag the corpse away if only to prevent the deceased from getting his items.
