Last Update July 3, 2025

Info

The head of the Akkadian Guild, he's worshipped by almost every bounty hunter in Rostach, though he seems to have some secret, inextricable link with CORG. He's usually looking after the residents of Rostach and loves adrenaline-pumping activities like arm wrestling. However, under that gregarious and friendly exterior seems to be some sort of hidden anxiety.

Gift

Cigar Cutter

Akkadian Guild members often see Marduk with an unlit cigar tucked between his teeth. Most onlookers understand why—cigars are a rare commodity in a place as poor as Rostach. Even Marduk, the head of the Akkadian Guild, usually has to take a frugal approach to smoking by just chewing on his cigars instead. Many have asked curiously how someone claiming to have come from poverty like Marduk could have acquired such an indulgent habit. Marduk never answers this question. Instead, he forces a smile, then transfers the little money he has saved up to the orphanage's account. Sometimes when no one's around, Marduk will discreetly light his cigar, take a deep draw, reminisce for a while, then immediately put it out and carefully tuck it away.
