Devidia II

Class-M planet in the Marrab Sector, home of a species that existed a fraction of a second out of phase with “normal” time and thrived on neural energy stolen from dying lifeforms. Upon visiting Devidia II in 2368, Jean-Luc Picard‘s crew discovered the shapeshifting Devidians were travelling through time to 19th-century Earth to extract Human neural energy from victims of a cholera epidemic. Devidia II had been explored—or at least surveyed—before 2368, since it was known to be the only home of the one-celled microorganism identified as LB-10445.^[1]
