Welcome to Continentia
The planes of existence are made up of the intermingled screams of Solaria and the Abyss. As you might imagine, that makes for strange and unstable realities. However, one plane of existence doesn't suck too bad and is mostly hospitable. The plane of Continentia is a stable place, if otherwise unremarkable. The most notable feature remarked upon by inter-planar travelers is the presence of several continents, giving rise to the generally agreed upon name of Continentia (many Orks still prefer to call it "Orkhomegreatfood").
