Kingdom of Darkness (KoD, a Novan hell): it is where souls went that were not incorporated into Holis. They supposedly became ignorant, devoid of knowledge about themselves or their surroundings. They saw the beauty of Holis — it was the one thing they are given knowledge of. Any yet, they must remain as perpetual outsiders, wraiths wandering the universe, bound to no one but themselves, living eternity in utter isolation, craving enlightenment, yet never receiving it. Legend has it one such being received enlightenment, and he used this knowledge to rip into Holis, letting other ignorant souls within. This threatened to unravel Holis, until another came, named Honabre. What he did was lost to history, there are many variations on what he did. The result was Holis was restored to balance.
