Nihilus

Nihilus is the name given to the ancient inventor of evil. He is understood to be older than the gods and is sometimes thought to have been the first fiend. He is defined by his decision to seek what lay between the Threads of Creation, outside of the will of Evendur. Despite the warnings of the angel Teveria, Nihilus dove into the gaps, commonly called the Interstice, where he is said to have built the Kingdom of Naught.
