Manganese

Manganese [Maggy: a general nickname] [Mags: Bismuth’s nickname]

One of the crowns and their powerful lineage, Manganese has always been gifted. When Bismuth volunteers to protect her, she can’t think of anyone better for the job—if someone has to do it at all. He’s been her friend since forever, and when he’s almost rejected from the position for his low status, Maggy stands up for him. 

She’ll always stand up for him.
