[Dreamscarred Press] New playtest: the Rajah, an akashic initiator!

[GreatGoatEater]

Hate to start off with such a morbid question, but here's one concerning The Treasury Heraldry

The Treasury (Su): Your unseen servants can conjure your personal treasury as a full-round action. This functions as an extra-dimensional storage space that appears as a heavy, wooden chest holding up to 50 lbs per class level plus 50 lbs per point of initiation modifier. When dismissed (a full-round action on the part of the unseen servants), any creatures inside the extradimensional storage are ejected, and the treasury, along with its contents, teleports to a secure location on the astral plane.

What happens when a Rajah with this ability dies? Does the chest stay on the Astral Plane, its contents lost forever until someone finds it?
