West past the Century Mountains, over the tableland of Cather's Basket, lie the secrets to the cruel syndicates  that threaten your livelihoods, your friends, and your city. Before you can solve those mysteries and keep the city safe, you'll have to make your way up through the clouds, among the bird-people, whose fantastic spires, floating nests, rope-bridges, winged ladders, and filigreed beauty won't protect them from their own civil strife. Can you resolve-- or avoid-- the fight for their throne, and get past their haunted gatehouse, and protect all you held dear, back East?
