Summoning

Do not call up that which you cannot put down. — H.P. Lovecraft, "The Case of Charles Dexter Ward"

Do not call up that which you cannot put on hold. — Principia Discordia

The power to summon forth an object or organism. Opposite of Banishment.

Capabilities
The user psychically transports the person, creature, or object of choice by means of teleportation. This may also result from a previous summoning contract, which creates a connection between the summon and summoner.

High level users can summon forth powerful beings or "familiar spirits" and often require strong mystic connections to where these entities reside. Users can call upon fairies, angels, demons, or animal spirits, just to name a few. The summoning can backfire, however, leading to any number of misfortunes, such as the summoned person, creature, or item causing harm to the summoner.
