The Drain
From ThornsWiki
The Drain is the name given to the newly formed rival trade route in Old Rose. The Drain is currently taking away profits from The Vein, hence its colloquial name. Silas Hawke is trying to figure out who runs the Drain; so far, the only clue is the name "Lord Sparrow" and the symbol of a once-famous armored ship known as the Warbird.
