High Evolutionary's Fortress
A fortress located at the center of the Savage Land, from which the High Evolutionary opperated the technology which created the Savage Land and mutated the life there into its current form.
In order to prevent him from expanding the Savage Land to the rest of the world, James Rhodes , Carol Danvers , and Aikku Jokinen (assisted by Ka-Zar's Tribe) succeeded in sabotaging the machinery and trapping the High Evolutionary inside his fortress.
He has made a number of attempts to escape, but to date these have all been foiled by Ka-Zar's tribe and their allies.
