Cthulhu Wars: Great Old One Pack Two adds four new Great Old Ones to Cthulhu Wars, and all four are available to each faction on a first come, first served basis. If you awaken Father Dagon first, then no one else has access to her...unless they can kill her and reawaken her for themselves. Each Great Old One has its own special ability, plus its own unique spellbook, which is earned separately from your own.
