A Sylie is the equivalent of a Den-Realm for the Ananasi. It serves mainly as a connection to Ananasa and a resting place to ease the transition to the Umbra. A Sylie is woven between the strands of the Pattern Web and is in no way recognizable as the resting place of a werespider. Most Ananasi choose to feed within their Sylie, luring their prey into it and making sure they return.
Most Ananasi choose urban environments for their Sylie, such as appartements, abandoned cellars and even cabinets.
