The Chaos Maelstrom is a storm of entropic energies that merges with a world's normal storm. Normally they drift aimlessly about the Web of Magic, a pollutant that even the mighty weave spiders cannot rid. Sometimes, these storms of chaos, powered by the same energies that course across Chaos, find a breach. A mini-rift or other anomaly unleashes this raw storm of chaos into an area. Like Chaos, the effects are unpredictable, with rivers flowing in the opposite direction, grasslands changing colors, creatures becoming mutated, or large landmasses changing shape.
Benevolence in a fit of unbridled rage, battled Kesserine ... with each blow from her mighty sword of pure whiteness, the sky cracked with thunder. Kesserine fought feebly against such passion and rage. After a day of battle between them and their armies, she was slain. Her essence merged with the Weave, becoming a storm of chaos, the Chaos Malestrom. The sadness and grief of what had been produced in the false marriage and the death of the wife he still loved was too much for Benevolence. A year to the day later, at first his body froze in place, then it petrified, rising up into the clouds in pursuit of his lost wife. It did not leave this world, instead it was trapped on our side of the Web, left to drift on the Weird Flow.

In 1296, sorcerer-scientists of Neeth-Theen's Mutation Labs summoned more than fifty creatures from Limbo. This summoning temporarily weakened the energies binding the Web of Magic. As a result of this, a storm of chaos came through a rift called the Sink of Chaos. Aettein's northern tracts were forever changed by this event. This chaos infused area is today called Flux.
In 1829, the Chaos Maelstrom is blamed for freezing a large area of Nautrek. It is thought that the sea was frozen by elements from another realm. The freezing of the sea created a temporary land-bridge between Elemantum and Brucrumus. This was followed by a rupture in the Elemantum Boundary Ward. This hole allowed a large Flaemis army to escape Elemantum and cross over to Brucrumus where they attacked Mogdúlg and then went on to join the Flux Pact.
The Chaos Maelstrom is an invisible, chaotic force that can be thwarted but never completely blocked and contained by the higher powers.
