Unified Creation Theory
From BelegarthWiki
This refers to the "Belegarth Monsters Unified Creation Theory" that pushes a vision where all Belegarth monster lore is interconnected. It encourages loremasters to create stories where all our gods and stories are real and they all interact in the same universe.
Loremasters among the goblins, ogres, orcs, gnolls, Khajit, and others have pushed this movement.
