This spell indirectly caused the first Floating City crash in Netheril's history.
And because that Floating City was named Sunsrest, the spell was thus named—Sunsrest's Sunburst.
At first, this spell under experimentation seemed to have succeeded, especially when witnesses in a neighboring city said:
At the time, they saw a brilliant, dazzling light shining across the western horizon. But then, within mere minutes, deafening booms rang out one after another, roaring and echoing as though right beside their ears.
After that, everyone who witnessed the terrifying sight was seized by utter fear.
Under the massive blast, the entire Floating City was torn into fragments of ruined walls and broken structures, raining down upon the vast earth below.
No one survived that terrible disaster.
Yet this devastating spell was ultimately remembered by many Arcanists, who continued trying to reconstruct and retrace it in later years.
Unfortunately, the endless light, heat, and terrifying energy unleashed when the disaster erupted made it difficult for Arcanists, even using spells such as [Time Regression], to fully determine what accidents had occurred during the spell's final preparation period, leading to a catastrophe Netheril had never seen before.
But there was one shared conclusion: the root of the disaster seemed to be that the energy required by the spell had exceeded the controllable threshold, causing a leak in the Mythallar's energy network. This, in turn, led to a fatal collapse of the Spell Model and its premature detonation.
The horrific energy eruption and magical turbulence even damaged the Weave in this region for a time, turning it into an area of chaotic Weave.
As the name implied, in such a violent Weave region, you might clearly be preparing to cast [Restoration] on a dying comrade to ease their local injuries, only for it to become [Steal Life]
