LTT 17897 III is a carbonaceous planetoid orbiting the dim M4 star LTT 17897. It is notable for the signs of massive nanofacturing on the surface, constructed approximately 502 AT, long before First Federation explorers reached this system.

It is believed that these structures were used to launch von Neumann probes outwards, but no other evidence of the builders have ever been found and no aioid clade claiming descent from Charybdis has been contacted. The defenses appear similar to those found on Duoden Torus.
