Vohoin

Vohoin is or was a fire spirit who pledged to perform a task for an Efreet they had summoned from the City of Brass in exchange for enough of the Efreet's spark to survive the winter without wood. Under the terms of this agreement they were also prohibited from contacting the City other than to contact their patron.
They later related this information to Zonda when she sought a solution to Alice's terminal spirit mismatch. Vohoin later came across Balvan after Alice had been turned by Swayne, and Balvan asked them to pass on to Zonda (who had departed to the Astral Sea) that Alice had flown.
