Mirrodin's Core

Mirrodin's Core, called Tav Rakshan (Hall of the Eternal Sun) by the leonin, is a massive globular space within Mirrodin, utilized by Memnarch to control the outer world.
==Description==
Mirrodin's Core can only be approached through five lacunae, one in each land of Mirrodin. At the center of the globular space, suspended in the air, is a blinding circle of bright light. This ball of pure mana is known as the Mana Core.Darksteel Player's Guide. (2004), Wizards of the Coast. Mirrodin's Core provides a brilliant and otherworldly sight, with shining metallic surfaces everywhere, reflecting the intense light of the Mana Core. Living in it were many hundreds of Memnarch's artifact creatures and constructs. The Panopticon, once Memnarch's lair is also located here, just below the beaming Mana Core.
It was from the Mana Core that the four suns emerged into the sky in Mirrodin's distant past, with the fifth being a recent addition. This event puzzled both the plane's Guardian and its denizens, eventually leading to legends about the nature of the five satellites. Mycosynth towers also dot the metal innards of the plane, though their arrival is also something of a mystery. The truth is that the mycosynth was a product of the glistening oil Karn had unintentionally brought to the plane, which created the mycosynth as the first step towards Phyrexianizing it. The existence of the suns was a result of Dominaria's time rifts, which destabilized Mirrodin's core, causing it to gradually discharge the five orbs of mana.
During the Phyrexian takeover of Mirrodin, the Phyrexians drilled holes into the core and it became one of the three spheres of New Phyrexia. In later development it became the eighth sphere called the Mycosynth Gardens.Jay Annelli. (2022.) Magic: The Gathering - The Visual Guide, Wizards of the Coast. ISBN-13 978-0744061055.
===The Mycosynth Gardens===
The Mycosynth Gardens are the eighth sphere of New Phyrexia. Towering columns of mycosynth grow unchecked here. Norn forbids any visitors to this and the lowest layer without her invitation, including other Praetors.
Within this layer is a gateway leading into the Seedcore. It appears as a piled-up structure of fungal strands that twists into a mimicry of entrails. It infects anything it touches. As someone approaches the gateway, it heaves, pulsing, before opening into a terrible hole into darkness ringed with waving tendrils.
