As soon as he was too close to the tunnel, the concentrated nightmare energy around him abruptly became aggressively active, which then rushed into his right hand.
Angor was rather surprised by this because he just made sure his right hand was "switched off". Somehow, the hand decided to absorb nightmare energy on its own.
Like always, he couldn't tell where all the surging energy disappeared to. But unlike the previous cases during which drawing nightmare energy didn't leave any noticeable effect on him, he began to feel faint and drowsy as if he was slowly falling asleep inside a dream.
As more and more nightmare energy went inside his right hand, those glowing sigils also grew in number until a large swarm of them danced around his hand like bees protecting their hive.
As they moved, they slowly painted a shining ring in the air, which floated away and reached the plane barrier ahead.
