These basilisks were populous in the salt flats of Thousand Needles. However, the cataclysmic event of the Shattering caused the salt flats to be completely submerged by water. The basilisks drowned. For the dead version of the NPC which is in the game, see Saltstone Basilisk.
The NPC was an objective of the obsolete quest, A Bump In The Road.
