All's Well that Ends in the Well

Hostile sylphs who would rather see the Twelveswood burn before making peace with the people of Gridania have begun using their forbidden magicks to charm the forest's creatures into doing their bidding. Temporarily enhanced by the spells, these turned creatures now possess the ability to enfeeble their victims with terrible poisons and wide-reaching attacks. Only by slaying the renegade sylph leader Briaxio of the Well will the creatures' minds be freed.
