Levi had several reasons for doing this, aside from the fact that the Kas Mountain Range was unsuitable for development.
From a military perspective, even if the iron mine were captured, the enemy couldn't take the ore deposit with them. He would have plenty of time to fight a war of attrition with those vying for it.
He could even let them have the iron mine for a while, wait for the various groups to beat each other's brains out over it, and then come back to clean up the mess.
But if High Cliff Castle were located here, they would be forced into a defensive war, putting them on the back foot the entire time.
No one rejected the proposal. Faced with Levi, who clearly possessed exceptional military insight, they felt no one else in the room could compare.
Although they didn't understand the deeper reasoning behind it, they knew they couldn't go wrong listening to their Lord.

With the war over, it was time to return.
