Trivia

 * Trius was originally meant to appear at the camp site as a bandit mage, starting the quest Trius' Trinket when talked to. The quest however has never been finished by the developers and is left incomplete and inconclusive inside Skyrim's datafiles, giving only mention of the quest's objectives and the intended reward, an undisclosed spell. The incomplete quest has the ID-name dunShipwreck04QST.
 * During Trius' Trinket the player would have been tasked with retrieving a small jewelry box from the wreckage below the sea. Once the box had been obtained, Trius would have taught the player an undisclosed spell.
 * There is no mention of Shelly in the original quest data. As Trius was meant to be a bandit mage, along with the original quest title hinting at a trinket, it's likely that Shelly's background story is a mere stop-gap for the much more elaborate story the original quest would have brought.
