Overview: 

The great magi of the Deathless Empire perfected a dangerous art long before the beginning of time: Maelarchor, or Conjuration. The Conjurers of old learned how to send their wills out into the spaces Beyond, contacting the dread presences of Chaos.

In time they learned to summon all manner of Demons, devising arcane Binding Incantations to command them. Most of the original Elvish secrets have been lost, but some latter Conjurers still practice this dangerous art, calling forth the minions of Chaos to use as servants.
