In the 2360s, Hekaran scientists Rabal and Serova attempted to convince the Federation Science Council that cumulative exposure to warp fields was destabilizing the Corridor, which would eventually render their homeworld of Hekaras II uninhabitable. Unable to convince the Council to take prompt action, the two took to placing signal buoys rigged to produce verteron pulses inside the Corridor to call attention to their findings. In 2370, these buoys disabled the USS Fleming, a Ferengi D'Kora-class marauder, and the USS Enterprise-D.
