Corruption

The presence of this beast was alarming but it did not surprise Rowan.

"No one is innocent," he drawled as he urged the spread of Retrogression to proceed faster, disregarding the cries of fury and astonishment from the outside–universal creature.

The spread of this taint of Retrogression was almost at sixty percent, but with the urging from Rowan, spurred on by the Runes he had implanted into the treasure, it began to rapidly spread and only a small portion of the hilt was left, but that would not last long.

During the brief moment he had spent with this creature, they had both tried to one-up each other.

Rowan had infiltrated inside its body with his Berserker Clones and he had kept them dormant, waiting for a while until the Creature would most likely lose any suspicion about their transaction, and when he also got stronger, the Creature had also played him too as expected.
