The first thing the others brought back was quite interesting. It was a water freezing reward.
It was exceptionally difficult to freeze salted water for obvious reasons and oceans in higher Dimensional worlds were even more resistant to such things. The Heir Wars planet had poles, but they weren't frozen over as one might expect, or more accurately, the waters that ran through it weren't. This wasn't only because the waters were salted, but also because the ocean of this world was akin to a very wide river, constantly moving about and "orbiting" the planet.
The freeze reward came from an Heir-Grade Dungeon, and it could be used in two ways.
The first was to build a bridge. If Leonel wanted to, he could build an ice bridge from his current territory to the other side of the ocean. This bridge would be exceptionally deep and thick, destroying it would be hundreds of times more difficult than breaking down the walls of an Heir-Grade city.
