====Artificial Planes====
* Mirrodin - Originally called 'Argentum', it is an artificial plane constructed by Karn. It is the only artificial plane known to have survived the test of time and is stabilized by its five artificial suns. When the mad construct Memnarch was left in control he imported creatures from countless other worlds to create a diverse ecosystem in which to raise planeswalker sparks for harvesting. The only true natives of the world are Blink Moths. A unique effect of the mycosynth lattice of the world is that organic creatures become metallic over time and metallic creatures become organic. The phyrexian oil left here by Karn has since given rise to new Phyrexians.
* [[Phyrexia]] - Phyrexia is an artificial plane of entirely mechanical "life" created by an ancient planeswalker. The nine-layered plane of artifice was discovered and rebuilt by Yawgmoth, and he staged his millennium long plan of Dominarian invasion from here. It's fate since the end of the Phyrexian War and the return of Phyrexia remains unknown.
* Rath - An artificial plane constructed by Yawgmoth, it was designed to be utilized by the Phyrexians as a staging point to invade Dominaria. Created out of flowstone generated in the central Stronghold, the plane slowly expanded over centuries until it was the same mass as Dominaria itself, at which point it would transpose atop the target plane, carrying its armies directly into the field.
* Serra's Realm - Serra's Realm was an artificial plane of beautiful cloudy skies created by the planeswalker Serra from pure white mana as a heavenly ideal. Serra made it in the hopes that she could make a haven where suffering could be avoided forever. It was the original home of the famous Serra Angels, and existed in peace and worship of its creator for some time until Phyrexia invaded and it was collapsed into the powerstone core of the ''Weatherlight''. At some point after the destruction of the ''Weatherlight'', Serra's Realm may have come back into existence in some form.
