Not much is known about the current elder of Shady Sands as of the events of Fallout 1. He is one of the oldest residents of Shady Sands, and has been living in Shady Sands for a long time, possibly back to when Aradesh first founded the town.
Stop the Radscorpions: Although cut from the final game, the Elder would have told the Vault Dweller that there is a nearby cave populated by a pack of radscorpions that could cause some damage to Shady Sands.
The Elder as a talking head can be seen only in pre-release Fallout 1 materials, and certain merchandise or packaging (see below) and does not appear as a complete set of images, only a single frame. The image/head itself appears to be identical to that of Morpheus' head.
