Summon Pyros

The Summon Pyros ritual summons the powerful titan Pyros from his domain to do the caster's bidding. Doing so is highly dangerous, as he is greatly annoyed by such disturbance of his sleep and if the caster is not powerful enough, it will be his or her end!

To summon him, the caster needs to put a daemon skull, spider silk, sulfurous ash and a piece of blackrock into a specially prepared pentagram made of blood. Then, a red candle is placed into the middle and ignited.

Taught by Malchir in the Spirit Realm in order to gain access to the Great Stygian Abyss.

When cast, the Avatar is sucked into the Abyss seeming to indicate that Pyros escaped afterward, but no mention is made of this afterward.

Trivia

 * In the Bob White Plot, the summoning never happened, as the video was part of the plot where the Guardian shows Lord British false images, implying that the Avatar had freed Pyros to destroy Pagan.
 * This ritual is mentioned in the spellbook, which is written by a Britannian mage. It is not clear how the mage would know of this ritual.
