Trivia
While several quotes are references to the works of H.P. Lovecraft, certain quotes originate from other games, including Planescape: Torment and the Baldur's Gate series.

Several of the quotes seem to refer to the Old God N'Zoth and his expected presence in Vashj'ir (the "bottom of the ocean").
