Covenant of the sideways

The Covenant of Sideways was born centuries ago as a meld of three minor guilds struggling to rise from the underworld: the Peddlers' Corporation, the Explorers' Council and the Fraternity of Charlatans, a phony guild covering the activities of a group of assassins. On the surface the Brotherhood is a guild of actors, acrobats and caravan guides, but it actually controls Sarnath's black market and information network. Nothing is forbidden to a member of the guild, it's only a matter of money.  

The discovery of the ancient ruins has awakened the greed of the Brotherhood's shadiest members.

Choose your guild wisely, son. Bad things happen to those who don't...
