When it came to controlling the land, the underground, the sky and the sea- The Undead Empire was more than capable, ruling over all forms of landscapes with an iron fist, no biome appearing out of their reach, even the dire environments and weathers proved to be little more than minor obstacles in their quests to expand Death's dominion.
