Sandalphon is an angel best known for his close association with Metatron, whom he serves with unwavering loyalty. He's frequently depicted alongside Metatron and essentially functions as his right hand—handling heavenly duties and covering for him when needed.
Beyond that, there's surprisingly little concrete information about him. What fans and sources do note is his calm, steady demeanor. He doesn't seem prone to drama or outbursts; instead, he carries out his responsibilities with a quiet professionalism. His entire role, really, revolves around supporting Metatron and the orders that come down from above.
