Zelem's Nexus is the name given to the ruins of the once a peaceful planet called Nakto. When it's star, Zee-Nakto collapsed, Crogenitor Zelem spent the rest of his life building a massive planet-size cylindrical ring that holds all the planet's fragments. The Black Hole that Zelem's Nexus orbits around is called Wha Nakto. Although going unnoticed by most other civilizations, the battle between The Darkspore and The Crogenitors that took place there was later called 'The Nexus Massacre'.
The Nexus is contained within a gigantic cylinderical ring covered in thousands of small hexagon-shaped windows that continuously pulsate a blue light. The Nexus is now littered with the debris planet fragments, ancient fossils, crashed space vessels, and ruins of buildings. Many of the isles are connected by the energy bridges seen above, with one particularly long bridge, which allows players to see Wha Nakto clearly through a relatively small breach in the shield.
Crogenitor Merak accidently caused billions of deaths when he was working alongside Zelem. He accidentally shattered some of the shields that held in the islands' atmosphere, causing tons and tons of Zelemi, as well as their home isles, to be sucked into the vaccum of space and/or into Wha Nakto.
Beings from Zelem's Nexus are Called 'Zelemi'.
