Star Trek: Poseidon - The Birth of the Federation was a forum-based RPG series based after the conclusion of the TV series Star Trek: Enterprise. Formerly set aboard an upgraded NX-class starship, the Poseidon (NCC-07), it now takes place aboard the first of the Poseidon-class. Originally titled The Birth of the Coalition due to apparent inconsistencies in continuity caused by the last episode of Star Trek: Enterprise, that has now been explained as a schism in time that has since been repaired, placing the Federation's founding in 2161.
