Northern Tribes

The Northern Tribes are a group of people who live in the lands far north of The Empire, their society consists of small tribes scattered throughout their territory. The tribes are fairly modern, as they are shown to have buildings and steam working shops. Its largest city (possibly the capital) served as a powerful stronghold, with Numa Seika being a major hero within their military and the prince.

History
The tribes were attacked by the Empire due to the threat they posed by their rapidly-rising military strength. An estimated 400,000 inhabitants were killed when General Esdeath buried them alive during this military campaign and broke their hero's spirit before killing him. Esdeath's army is currently stationed there to continue watch over its people to prevent future uprisings.

A tribe of Danger Beast hunters called the Partas were completely wiped out by one hostile tribe that crossed the border into the Northern Frontier lands of the Empire. The chief of this clan was Esdeath's father.
