Taking Uldum's current conditions into account, Herad soon devised a safe mining plan.
Whenever a large section of the underground obsidian deposits had been hollowed out, he immediately packed it solid through controlled collapses.
Although this would leave depressions on the surface, it was better than a sinkhole suddenly appearing.
Controlled collapses meant the subsidence could be spread out.
A large underground cavity would collapse into a long channel on the surface.
The collapses appearing throughout Uldum became a network of channels that could all connect.
Once river water was diverted from upstream, the difference in elevation between north and south would carry it through most of Uldum.
The Tol'vir working away in the ruins were baffled to see channels inexplicably appearing in the distance.
What was going on? Could natural collapses look like this?
After staring at the channels before them in confusion for a while, they suddenly cheered in excitement.
This meant they would no longer have to trek across the desert. They could come to work by boat.
They could also plant crops and trees along the channels.
The Tol'vir all gave thanks for nature's bounty.
As for whether someone had created the channels with magic...
They immediately ruled out that possibility.
The channels stretched from the edge of their vision to where they stood, then continued all the way to the opposite horizon.
What spellcaster could instantly create channels dozens or even hundreds of kilometers long?
That was absolutely impossible!
The Tol'vir in the desert ruins all thought it was an accident.
In the large southern city near the river mouth, however, people knew someone had done it.
Not long after the water level in the great river dropped, a dam rose at its mouth.
The dam had a finely crafted structure and was very solidly
