BNIB:
The Sons of Ragnarok are a notorious outlaw biker gang, that could very nearly have become Acolytes of Sin themselves. However, their total rejection for following orders made any approach to try and conscript them to aid the sins result in a very dead servant of sin. This biker gang is obsessed with Viking mythology, with members assuming nicknames in reference to the Norse Gods. The realization that the Apocalypse (or Ragnarok, as they prefer to call it) was upon them stirred the gang into a battle frenzy! However, their contempt for authority also means they would never agree to join FAITH. Though that doesn't stop them from carrying on the fight against the Others on their own terms!
The Sons of Ragnarok Expansion box contains a full team of 7 heroes, including a Leader, 2 Fixers, 2 Snipers, and 2 Bruisers. These rebels tend to operate outside of FAITH, but they can be mixed and matched with any FAITH team as your group may choose. This team follows the same rules as any FAITH group, though they were designed with special synergy among themselves.
Each Sin provides the Sins Player with a different deck of Sins cards that can be played at different times to surprise players with different effects, often tied to the strategy of each Sin. Yes, because each Sin taints the game with an overarching mechanic that is always in effect.
