We haven't kept a very close eye on Syfy's angelic 'Legion' TV sequel 'Dominion' since its summer premiere, nor ongoing alien drama 'Defiance,' but fans of either are in for some good news. Not only will 'Dominion' return in 2015 for a second season, but 'Defiance' will launch a third run next year.

Per Syfy's announcement, either series will return in (likely summer) 2015 for 13 additional episodes apiece. Kevin Murphy, helmer of 'Battlestar Galactica' offshoot 'Caprica,' will continue to act as executive producer and showrunner to 'Defiance,' while 'Sons of Anarchy''s Vaun Wilmott will do the same for 'Dominion.'

For those who missed out on the 'Legion' TV sequel, here's how Syfy officially describes 'Dominion':

Based on characters from the hit theatrical film ‘Legion’ (2010), ‘Dominion’ is an epic supernatural drama set in the year 25 A.E. In this transformed post–apocalyptic future an army of lower angels, assembled by the archangel Gabriel, has waged a war of possession against mankind. The archangel Michael, turning against his own kind, has chosen to side with humanity against Gabriel. Rising out of the ashes of the 25-year-long battle are newly fortified cities which protect the human survivors. In Vega (formerly Las Vegas), the largest of these cities, two houses vie for control and the stage is set for political upheaval and a dangerous power shift. Meanwhile, a rebellious young soldier begins a perilous journey as the war between the human race and the fallen angels hellbent on their domination escalates.

‘Dominion’ stars Christopher Egan (‘Kings’), Tom Wisdom (‘300‘), Roxanne McKee (‘Game of Thrones‘), Alan Dale (‘LOST‘), Anthony Stewart Head (‘Buffy the Vampire Slayer‘) and Luke Allen-Gale (‘The Borgias‘).

Well, what do you think? Are you glad to have 'Dominion' back for season 2 and 'Defiance' for season 3?
