Arlen is a tiefling with deep mahogany skin and a pair of thick horns that curve forward like a ram. He often wears a rugged leather carpenter's apron over stained commoner's tunics. His tail is long and ends in a spade, frequently twitching with small sparks of static electricity when he is nervous. He has calloused hands and a gentle, weathered face that belies his infernal heritage.

Arlen is a humble and soft spoken man who still views himself as a simple village carpenter. He is slow to anger but deeply protective of those who cannot defend themselves. He possesses a dry sense of humor and prefers the company of honest laborers to the high-born.

Arlen spent most of his life in the quiet village of Oakhaven where he was respected as a skilled carpenter. During a season of terrible brushfires, Arlen stood alone against a wall of flame to protect the town granary. In a moment of pure desperation, he didn't grab a bucket. Instead, he felt a surge of raw, multicolored energy explode from his chest. The magic didn't just douse the fire, it turned the smoke into butterflies and the burning wood into solid stone. The village was saved, but Arlen was changed. He was no longer just a neighbor, he was a hero, and a frightening one at that. He realized his infernal blood had finally manifested a chaotic power he could not control. Fearing he might accidentally harm the people he loves, Arlen left Oakhaven with only his tools and a heavy heart. He now travels the world trying to find a way to harness the lightning in his veins while using his strength to aid the common folk in every town he passes through.
