Not much is known about the current elder of Shady Sands as of the events of Fallout. 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.
The Elder as a talking head can be seen only in pre-release Fallout materials, and certain merchandise or packaging (see below) and does not appear as a complete set of images, only a single frame. He does appear to be motional in the 1996 preview, but not shown talking. The image/head itself appears to be identical to that of Morpheus' head.
The Elder was to appear in Fallout, but was cut from the final version of the game, for unknown reasons. However, his dialogue file can still be found in master.dat, however it is unused. He also appears in the 1996 Vault 13 preview.
