As the explosion occurred, a large wave of wither spread throughout the surroundings while Arthur's transformation came to an end in tandem.
The ambient purple glow of his runes faded, turning them back into abyssal black and then fading away into his skin as if they were never there.
The necroflames shrouding his pale skinned arm also swished away into nothingness at the same moment, while his strength dropped back to his level.
On the backside of his left palm now, there was a new symbol. The mark of [Death].
The mark was larger than his [Darkness] mark but its opacity was lower than the latter.
An elaborate sigil, composed of intertwining ravens' feathers, skeletal hands, and a cryptic array of ancient runes, had manifested ominously on the backside of Arthur's palm.
