Odina

Odina was an island in the Matoran Universe, upon which was situated the headquarters of the Dark Hunters.

History
Odina was originally created by the Great Beings and intended to be part of the Matoran Universe. While the landmass' specific purpose remains ambiguous, it was one of the final islands to be colonized, remaining entirely unpopulated until it was annexed and settled upon by The Shadowed One and "Ancient" in the aftermath of the Grenok Ancient Wars, roughly 80,000 years ago. Notably, this pair of settlers were known to have constructed a fortress in the southern belt of the island, leaving the northern portion largely untouched.

With many residents of the Southern Matoran Universe harboring less favorable sentiments towards the Toa as Mata Nui's chosen species, The Shadowed One used Odina as a headquarters from which to rally support from warriors native to the southern universe, uniting them into a composite mercenary guild known as the Dark Hunters. For many thousands of years, the Dark Hunter ranks would grow and new operatives would report to the Odina Fortress to receive advanced training, undergo repairs, and for various mission briefings.

Following the Great Cataclysm, the Dark Hunters notably exploited the universal chaos to pillage vulnerable villages and cities, with a number of its members reporting back to Odina and being dispatched on missions to destabilize numerous islands ravaged by the universal shockwave. This period of turbulence and uncertainty also saw beginning of the Dark Times, a 1000-year stretch of armed conflict between the Dark Hunters and the Brotherhood of Makuta.
