Vahana

The Vahana was a large transportation device created by Kavrenthak, the Harmonic Architect of the Duuema. It was intended to transport the souls of living mortals directly to Celestia so that they could all live for eternity in paradise. However, the construction of the device was never completed, with the device becoming lost after the Vanishment.

It is believed by some that the Vahana was to be powered by the Soulstar, although no evidence of this theory exists.
