I know you don't wanna visit- [She makes a gesture as if to indicate "all the encompassing philosophical concept of death as made manifest in House Gehring's particular patron goddess" and also "your mom".] -too often, not the kinda thing where you wanna push your luck. But it couldn't hurt to do a summoning with this dude's name on it and see who shows, right?

[Unless the ghost in question is really angry...]
