They are a nomadic nation of outcasts, driven into hiding and driven for revenge. The Cloaks launch hit- and-run attacks against those factions whose ambitions they disagree with, and then scavenge what supplies they can from their victories.
The Cloaks rely on stealth and espionage to win their battles. Cloaks players know how to find the weaknesses in their opponent’s defenses and exploit them, cheating opponents of their best cards. Thieves force opponents to discard cards, and spies and assassinations keep enemy factions from using cards at ideal times.
