The archfighter is an Elven soldier son of a noble now renowned throughout his entire continent. His reason for earning this feat? Slaying 237 enemy soldiers in one day to avenge his comrades after an ambush. A few more peculiar things soon happened, such as his late fiancé's reincarnation as a sentient transforming weapon, and no less the weapon he killed those 237 with. With his fiancé having been a cleric, he gained the attention of the gods and by extent got his hands on some divine magic. With these newfound abilities, he went through years of adventuring to find some sort of purpose to his life, but in the end decided that settling down was more satisfying. So, using his intellect, he became the president of a trade company through marrying the daughter of the previous owner. Thus, he is most likely to be encountered by the coast or in large port cities.
As for his arsenal, Ryse's Revival is his love's new form, which is ironic since she's decent for killing despite being a kind soul. As for his Spell Sponge, that was a gift to him from one of his relatives that, by means still unknown to him, ascended into becoming a minor deity.
In terms of physical accomplishments, the archfighter has been able to kill well-grown men with a single punch, toppled a siege tower by ramming into it(it wasn't that well-balanced), and needs to use magical weapons against armored opponents or they will quickly shatter due to his sheer strength. He's also survived being impaled multiple times, brushed off a power word kill spell, and killed a basilisk while he was drowning.-->
