A Gamble

Arthur's mind turned hazy as chaotic mana was unleashed from within his body. The mana was dark purple and it didn't dissipate but kept surrounding him. 

Despite the overwhelming pressure from the chaotic mana, Arthur tried to store the artifacts before he was about to run away. He stole three artifacts before a roar shook the heavens and earth.

He looked up in surprise as he saw, through the broken ceiling, the dragon descending his way and leaving the Astra-ranker to flee. It was diving straight down as if its life depended on it. 

'What's going on? Why did it leave the Astra-ranker?' Arthur panicked as he threw the artifacts and tried to teleport away. The mana that was surrounding him, however, prevented him from doing so. 'Shit. Shit. Shit. What is this mana?' Arthur tried pushing it away, but it was unceasing and relentless.
