Vesimar is the mage-king who got out. He was a king of the Tolarian line in its final generation, one of its highest adepts, and by every account a true believer in the clean working, the dynasty's creed that magic must be torn into pure separate forms before it can be trusted. What set him apart from his kin was not doubt. It was timing. Vesimar left Elderran before the Apparatus of Severance was activated, or at the very instant Caedran threw the switch, and because he was outside the catastrophe when it broke, the severance never cut him. The survivors who came after gave him the only name he is now known by. They call him the Unsevered.
Whether he fled in cowardice or left on a plan is the first thing about him no one can settle, and he gives nothing away on the point. The mage-kings who stayed were killed, or frozen conscious at the center, or remade into wandering things. Vesimar simply walked out of the worst disaster in Alarian history with his mind, his power, and his convictions intact, and that single fact has shaped every century since.
They will tell you the mage-kings are all dead in their machine. They are wrong by one. I left before the lie went off, and I have had a long time to think about what we got right.
He should be long dead, and he is not. Vesimar carries a pocket of the stolen time-layer with him, a fragment of the same Izzus seam the Apparatus tore, bent so that his own span runs at a crawl while the world ages past him. The years that have buried whole kingdoms have spent him by handfuls. A man who should be centuries in his grave still walks, unhurried in the way time-shapers are unhurried, because for him a decade is closer to a season. The carried pocket is small, as such pockets always are, and it does not touch the true clock or anyone but him. It only keeps him.
What he wants has not changed since the day he left. Vesimar still means to build a magic worked perfectly clean. He treats Elderran not as a refutation of the creed but as a flawed first attempt, a design undone by errors he believes he now understands, and he is looking for the place and the means to try again with the mistakes corrected. This makes him the rarest kind of threat in Old Tolaria's account. He is a sane, patient, capable man, and he is pursuing the exact ambition that broke the region the first time. He is also the apex example of the region's oldest open wound, that the containment around the dead zone has leaked from the first day. Everything else that escapes Old Tolaria is a beast or a relic, some twisted thing that does not know what it is. Vesimar knows exactly what he is, and he left under his own power before the cordon ever existed to stop him. Where he is now is the question. He does not stay anywhere long, and a man with his patience can afford to be very hard to find.
