From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide
The Perseus was a battlestar from the video game. Some time after the start of the Cylon War, it liberated a Cylon prison facility that had been holding captives (including Galactica commander Magus) inside it for over a year.

This battlestar is part of a separate continuity that mixes elements from the Re-imagined Series and Original Series as well as unique material. It is not a canonical item in either series.
