A Seance is a small Descended From the Queen game, intended to be used as part of your ongoing roleplaying game. Whenever characters use spiritualism or necromancy to speak with dead spirits, instead of using your game’s normal rules, pull out this game and play it instead, to create a different sort of atmosphere as you pierce the veil between life and death.
You’ll need to print out the file and cut it into cards to play properly. I suggest printing 6 or 8 pages per sheet of paper, and then putting them into card sleeves, like you’d use for a collectible card game.
