well if anyone read the folio notes in tam tara hard. theyre pretty disgusting, honestly. Being palace of the dead, is probably just a purpose driven invitation to the WoL to finally kill them, drain them of aether and reanimate her beloved for good OR as for why wed need special weapons and armor could possibly have to do with her fall into the deep left her as a mere spirit, haunting the place with specters maybe? I mean obviously were traversing a separate realm from that of our own, maybe have to enter with aether weapons because she only exists in the aether now refusing to return to the flow, idk. those folios were really sick and a good read
