Sishir Canyon was previously a canyon completely taken over by monstrous Deepmoss spiders. Their eggs and webbing densely covered the whole area, and deep inside, the most powerful of their number Besseleth awaited. When Stonetalon was redesigned this area became the opened up Webwinder Hollow and a new canyon was added and given the same name just west of it.
