As a Whisperblade, Zelef Eryx is a spy and enforcer who hunts for danger and corruption within his Freeguild’s ranks.

When the Raven City – Lethis – is endangered by a mysterious menace, Eryx must join a crusade that will venture into the darkest reaches of Shyish. They search for the lost fortress of Udriste, whose near-mythical weapons and knowledge could save Lethis – if Udriste still exists.
