Cerulean Storm

The Cerulean Storm, in addition to being the title of the final book of the Prism Pentad, refers to a magical weather phenomena plaguing the Dungeons & Dragons world of Dark Sun after the events of the Prism Pentad novels.

Creation

During the events of the novel "The Cerulean Storm", the current ruler of Tyr and would-be replacement Sorcerer-King Tithian was involved in events that saw Rajaat freed from his prison in "The Hollow", an extraplanar void, in the lava-surrounded city of Ur-Draxa, the former home of the Athasian Dragon Borys. In that realm, Rajaat had undergone a transformation into a powerful archomental in his own right; upon returning to the physical world, his spirit became embodied as a monstrous giant with cerulean blue storm clouds in lieu of flesh, a living manifestation of his desire to restore Athas to its Blue Age. Thanks to the intervention of the mul sun cleric Rkard and the magic-amplifying Dark Lens, Rajaat's spirit was banished back to the Hollow, leaving the elemental matter of his body to disperse. But in the process, Tithian - who had been clinging onto the Dark Lens to try and wrest it from Rkard - was inundated with magic and transformed into an elemental; his soul became bound to the clouds, and yet he also became linked to Rajaat from his prison in the Hollow.

Present Day

The Valley of Dust and Fire is now called the Valley of the Cerulean Storm; the lake of lava and the ruins of Ur-Draxa have become obscured by swirling blue clouds, lightning, rain, and boiling steam. The storm's duration can't be determined, but it shows no indication of abating any time soon.

Trapped in the Black yet tied to Rajaat in the Hollow, Tithian can interact with Athas's physical dimension in only one way - through the Cerulean Storm. His rage at his failure manifests as wind and lightning, while his frustration and loneliness falls like bitter tears, a torrential deluge of cold, stinging rain. He has become, in effect, a spirit of water, haunting the valley and inadvertently protecting the Dark Lens that could otherwise be used to free him. Tithian's violent storm, and the scalding steam it produces over the lake of lava, prevents rescuers from reaching the Dark Lens.

The storm over Ur Draxa is an aberration produced by the intermingling of powerful supernatural forces, and appears frightening to even the hardiest, most well-traveled adventurers. The effects of the rainfall on the molten lake, like the great clouds of boiling steam, have created hazardous conditions that have left Ur Draxa uninhabitable.

Effects on Athas

The Cerulean Storm calves off smaller storms that then go racing through the Tablelands frequently; known as "Tyr-Storms", these offshoots hit a region of the Tablelands at least once per month, though no region sees a Tyr-Storm more than once per year. They last an average of 20 minutes to an hour, and whilst you might think they're doing a good thing by returning water to Athas, the fact is they hit with immense and indiscriminate destructive force, leading to them being destructive and often causing casualties when they hit.

Cerulean Wizards

Naturally, with a new source of magical yet elemental power available to it, Athasian wizards began tinkering with trying to draw power from it. This resulted in the debut of the Cerulean Wizard amongst the other kits in the splatbook "Defilers & Preservers: The Wizards of Athas".
