Reliquary of Yadisunu
The Rib of the Legendary Hearald of Bahamut
The party obtained the reliquary from the lair of Azu-Makeen at the behest of Basouk Khalinda. Indira Ére gave it to him in Akkarid while The Party was staying at the house of Adil al-Khayrat. His intent for this artifact remains unknown.
Asha Druj later revealed that Basouk gave or sold her the reliquary. To what end—and if he had another purpose for needing the artifact—remains a mystery.
