The Azathoth expansion is a unique "neutral" expansion. When you awaken Azathoth, or are the first player to summon one of the four Monster types associated with this faction, you get that unit's Loyal Card. This lists the Monster's (or Azathoth's) stats, gives his special ability (all Azathoth monsters have these), and so forth. From then on, only YOU can summon that Monster type. Monsters included in the box are: - Dimensional Shamblers - Star Vampire - Elder Thing - Servitor of the Outer Gods Azathoth is a Great Old One unusual in many ways. When he is summoned, you choose how much Power you want to spend, and place a special marker on your Power track. This is Azathoth's combat ability - so the more you spend, the more deadly he is. Of course, in some games, a person, fearing Azathoth's misuse, might summon it cheap and dirty just to keep it out of the hands of another player. That's all part of the fun.
