Long Live the Queen
“At first, the now-frequent deadly avalanches in the Coerthas highlands were written off as displays of Oschon's might. That is, until local mountaineers spotted a giant bomb sending smaller explosives up onto the Nail to self-destruct, triggering massive cataracts of snow and rock. Knowing now the true cause of the matter, the Holy See has put a bounty on the floating head of this "bomb queen." The task of regicide, however, will not be an easy one, for she is attended to by a retinue of royal subjects who are ready to serve her in any way necessary─including self-destruction.
