Time is the element that should not be possible, and the one that has made the most people rich. A shaper channels emotion through Izzus, the time layer of the Elemental Planes, and bends the rate at which things happen inside a small space: a moment stretched until a heartbeat's thought has ten heartbeats to finish in, a span hastened until rot races or a wound bleeds faster than the body can answer. The pocket is always local and always small. Step a foot outside it and the world keeps its ordinary pace, entirely unbothered.
This is the line that matters, because people hear time magic and picture history wound backward. Time-Kethic does nothing of the kind. The true flow of time in Alaria is the Great Cycle, the astronomical clock set by the drift of Aurus and Nydus, observer-independent and wholly past any mortal's reach. What a time-shaper bends is the local rate inside the pocket, the way a stone set in a stream bends the water around it without slowing the river itself. No one undoes a death or steps back into a finished year. The strongest time-shaper alive can make a single room run fast or slow for exactly as long as she can hold it, and no longer.
The feeling Izzus answers leans away from the present. Patience most of all, but also foreboding, the sense that something is on its way; regret, which keeps turning back toward what already happened; anticipation, which strains toward what has not. A shaper who lives naturally in that register works the element cleanly, and a hurried, present-tense temperament gets almost nothing from it. This is why time-shapers are unhurried to the point of unnerving the people near them. The stretched calm of Besnoumeru's Oracle Merchants is not an affectation. The work selects for it.
The element's particular failure is drift. A time-pocket wants to slide off the moment it was aimed at. Regret drags it backward and the stretch settles a beat behind its mark; anticipation overshoots and it opens too early or runs too long. Holding a pocket exactly where it was meant to sit is harder than opening one at all, and a time-shaper spends as much practice on aim as on strength. A drifting pocket is the small version of the hazard. The large version is the seam itself, which can be torn, though almost never is. That is the Torn Hour: the one time a school of Vyanoweir cartographers tried to inscribe an Izzus seam in Deoric, the writing tore it open, and the Plains of Oblivion are what remained. Older breaches than that are rumored in the deep past, undated and unnamed and beyond any record. The seam has been torn only one other time anyone kept account of, beneath Elderran, the capital of Old Tolaria, where the Tolarian mage-kings built a machine to seize the time-layer outright and tore it instead. The ruined city has run slow ever since, its local rate dragging toward a standstill at the center while the world a few miles off keeps its ordinary pace. The general Kethic measures hold (see Kethic): magnitude rises with the intensity of the feeling, and efficiency with how true the register runs. But with Izzus, the precision of timing is a discipline of its own.
They all have the same look, the ones who work Izzus. Like they have already heard how the conversation ends and are waiting, politely, for the rest of us to catch up. — a Tarkhetan factor, on the Oracle Merchants of Besnoumeru
That is enough to break a market. The Izzus leyline surfaces in Besnoumeru, the second city of Nektuna, where the seam runs shallow enough that a trader standing over it reaches far past what the same trader could manage in any ordinary town. The local time-strangeness is an open secret and a closed business. Besnoumeru's Oracle Merchants do not foretell prices, whatever the name suggests. They buy themselves time the rest of the floor does not have, a stretched moment to settle a contract, weigh a rumor, and act on it before a rival has finished reading the same report. Deals worked on the seam close with an accuracy that looks like prophecy from the outside and is really closer to having read the last page first. The syndicates that hold the best access to the seam guard it the way another city's gangs guard a wharf. Besnoumeru is the eastern node, and the trading edge is only one use the seam can be put to. Far to the west, the same Izzus layer surfaces again beneath a salt-white island in the Shattered Sea, where the seer the pirate isles call the White Oracle works it for judgment rather than profit. She sells counsel to a lawless clientele beyond Tarkhon's reach, and the answers that look like prophecy from the outside are the same trick the Oracle Merchants run on the trading floor, turned on a captain's life instead of a contract.
