Delphi Ardu System

Name of a star system with 11 planets, unexplored as of 2363, one of which became the site of the first direct Federation–Ferengi contact initiated by the U.S.S. Enterprise NCC-1701-D on Stardate 41386.4. Class-M but with no sign of native lifeforms, according to previous long-range scans, it was found to be one of several defensive outpost planets of the long-extinct Tkon Empire. Its force field, energy-draining weapon, and automated “guardian” were, amazingly, still functional.^[1]
