It is the magic spell that was on a staff that could raise the body of a person who died. Do you think that should be in Skyrim? I think it would be cool and should be a conjuration magic spell.
Also, wouldn't it be cool if you can summon things longer than 120 seconds?
This spell has already been in the game. It was in Oblivion in three incarnations, it was the Staff of Worms, the spell Reanimate and the greater power Risen Flesh from the "Ghosts of Suicide Hill" quest. So yeah, it's possible it will be in Skyrim too.
