Shadow Realm

"'As for Erebus's champion? Most of his dangerous abilities were also countered by being in the air since there weren't surfaces for players' shadows to cast on them!""Still, he was a scary opponent to face off due to him being a Shadowborn. This race was one of the top 30 strongest races in the universe.""They were known for having the ability to travel between the Matter Universe and the Shadow Realm.""No one had seen how it looked like but them since the realm was completely separated from the Matter Universe with its own set of laws.""Hence, filming, taking pictures, or connecting to the Queen was impossible...Just like being in a separated dimension.""The only information about it came straight from the shadowborns themselves.""All of them proclaimed that it was filled with shadow element natural treasures that could make any shadow Elementalist salivate.""Probably due to having access to an entire realm filled with those treasures, the race had gained enough strength and status to place itself within the top 30 races in the universe.""Felix had a feeling that the shadow Primogenitor Erebus was the one who created the Shadow Realm and was currently residing in it.'"- Chapter 525

Talented ShadowBorns can Transport themselves in and out of Shadow Realm and objects with them but they have to protect them from the Laws of the realm."'Unlike Felix had expected that his parachute would be returned in the same state, they already knew that his parachute was a goner the moment Saltz Master died.""That's because objects transported to the shadow realm would be subjected to the laws of that realm.""They weren't friendly in slightest to anything that wasn't a shadow or had tremendous affinity to the element.'          -Chapter 544"
