The Artefacts of Power

(from the Scroll of Percivalos)

The Artefacts that make such a thing as the complete destruction of the Cosmos possible contain power beyond mortal comprehension.

On the last day that Haven existed as an intact world, the nature of the seventh artefact was discovered. It was not, in fact, an artefact at all but a powerful spell, Spirit of Power, cast to summon Raziel Mallaithe and give him corporeal substance, in the process demanding of his priests the "ultimate sacrifice".
