Quests

 * Annotated History, Under Observation: ?
 * Warden Contract: The Watcher may release the vithrack from their perpetual service as wardens of the Collections, making them friendly to the Watcher. In order to do this, the Watcher must already have the contract on hand when encountering Sissak, as he will not let you leave to fetch it. Without the contract, a fight it is.
 * He gives you and The Third Eye as a reward for finding the contract.
 * Subsequently, all the vithrack enemies in the Spun Terrace will no longer be hostile. In addition, Vessatraz will appear in the southeastern corner of the map. She sells the Vithrack Silk Slippers, and an assortment of drugs.
 * If you pass either a Metaphysics 15, History 18, or Streetwise 13 check in doing so, you'll also get: 2x Scroll of Major Healing, 2x Scroll of Torrent of Flame, Scroll of Chain Lightning, and a Scroll of Rusted Armor.
 * Note that if you have Serafen, Vatnir, Ydwin, Aloth, Maia, or Fassina in the party, their reactivity to the Watcher passing one of the above skill checks will cause the dialogue to end prematurely and you will not receive any rewards. Swap these companions out, or pick one of the non-check dialogue options in order to work around this issue.
