Technolith

Technoliths were massive structures found on the artificial world of Iokath. Build by Iokath creators and maintained by droids after the Iokath civil war left no organic life on the world, the Technoliths served as access points for the massive network of information storage spread across Iokath. They could function as holo-terminals for live communications, relay archived messages and otherwise provide access to the massive amount of data that was several millenia old by the time Iokath was re-discovered in 3631 BBY.
