Okay so far what I've put together is that there are monarchs for different elements, remember on the ant island towards the end where 2 entities were walking and one of them dropped all the hunters there and put them to sleep. Im pretty sure in the beginning when Sung was on the altar he was possessed by the shadow monarch or perhaps the shadow monarch is lying dormant in him. My proof is when he was fighting tusk, tusk asked if sung was the monarch because of the aura that was coming out of him, also when the 2 entities were walking through the island they said they sensed the shadow monarchs energy and they pondered as to why he would help the humans. Remember when the chick that breaks through peoples limits peered into him she exclaimed that something was staring back at her giving further proof to this theory. Let me know what you guys think.
