From The Heretic Knowledge Vault
The graveyard in Santuariel where Ian's mother and sister were planted, following the former's suicide by incineration (which just happened to incinerate her daughter as well). Ian and Meji have made a sad pilgrimage there, with messy consequences.
We don't know yet of any other significant Living Impaired characters who repose there, but stay tuned. As an amusing real-world aside, Los Alamos, New Mexico, birthplace of the atomic bomb, is also known colloquially as "The Hill." Could this be a harbinger of things to come when Ian "goes nuclear"? Who knows?
