Daimon
“Daimon” is the original Greek word from which the modern English “demon” is derived. The Greeks regarded the daimon as an intermediary between the gods and man, distinct from the free-roaming malevolent spirit of Mesopotamia. Comparable to other Paths’ guardian angel, faerie kin, power animal or ancestral protector, the daimon shares an intimate personal link with the bearer of this Merit, but also partakes of the Supernal Realm that is the daimon’s birthplace. A mage’s daimon is far older than the mage, at least in an ontological sense, and has access to knowledge, wisdom and modes of thought or being that are beyond mortal ken. Mages of any Path can purchase this Merit.
This Merit acts similar to the Dream Merit. The mage with this Merit, however does not need to spend an hour in sleep or trance to receive a clue from his daimon. He merely spends one turn in meditative concentration, and the Storyteller rolls his Wits + Composure in secret, with the same results as described for the Dream Merit, except that success provides only one clue. This clue comes from the daimon, and similar to dream clues, is cloaked in allegory and metaphor.
