On the western shore of Deadman's Lake stands the Salt Tomb, a burial structure raised from blocks of white salt. It predates any local memory. No one recorded who built it, and no one knows who or what lies sealed inside. By every rule the structure should be gone. Salt left out in the weather dissolves; a building of it on a cold lakeshore should have slumped to a white smear in a few wet winters. The Salt Tomb has stood for centuries and lost nothing. The blocks are as square and as bright as the day they were cut, because inside the tomb the dissolving has barely started. Time runs slow there. Not stopped, slow, slow enough that a thing which should take a season takes an age.
The cause is a localized Izzus stall. A minor time leyline surfaces beneath Deadman's Lake, and where it touches the tomb it did not rupture or run wild. It stalled. The local rate inside the structure fell toward zero and set there, locking the whole burial out of the pace the rest of the world keeps. This is the same flaw that makes an Hourbound, an Izzus stall worked so deep into a thing that its clock comes loose from the world's, except that here the stall took a building instead of a person. Nothing cosmic happened. The Great Cycle ran on past the Salt Tomb the way it runs on past everything. What changed was only the rate inside one set of walls, the way a stone set in a stream slows the water turning behind it without slowing the river. The river never noticed. The water behind the stone has been sitting nearly still for centuries.
The danger is not the stalled core. It is the edge. A stall this deep does not ease off gently at its boundary; the rate climbs steeply across the threshold, slow within and ordinary without, and the gap between the two runs fast and violent. The people who have tried to break in learned this through their tools. The salt turned harder than stone and took every chisel, and the one party that tried tunneling underneath watched their iron corrode to rust within the hour, years of weathering crowded into a single afternoon at the boundary where the quick rate meets the slow. Anything held too long against the wall comes back aged out of its turn. Whatever might be done to open the Salt Tomb has to cross that edge, and the edge is where the strangeness does its work.
A miner's pick left leaning against the tomb wall at first light. By midday the head has gone to orange flakes and the haft is still sound oak, because only the iron crossed close enough to the salt to feel the edge of the stall. The handle has not aged a day.
Nothing lives at the Salt Tomb. A stalled pocket offers nothing to feed on and no rate at which to feed, and the boundary, the one place anything happens at all, kills too quietly for any animal to stay and learn the lesson. What is sealed inside is not known, and the stall makes that question stranger than an ordinary tomb's. If the local rate truly fell near zero when the stall set, then whatever was laid in the Salt Tomb has hardly aged since. A body interred a thousand years ago could lie within as fresh as the week it was buried, having spent in there what amounts, by its own slow clock, to a few days. No one has reached the bottom to settle it. Those who study the Hourbound point to the Salt Tomb when they want to name the worst a stall can do: a place so completely held out of its own time that nothing within it has moved toward any road, or toward anything at all, in living memory, and no sign that it ever will.
