Marcerine is a pony witch and former member of the Fists of Mercy who served as Ping Wing’s mentor and guardian in the underground Marrow Kingdom. Despite her role as a teacher and protector, Marcerine was later revealed to be connected to the Coven, the organization that secretly controlled the kingdom as a social experiment.
Background
Marcerine claimed to be from the surface world, having come to the Marrow Kingdom as a young filly with her father. Her father was revealed to be a Coven agent who disappeared only weeks into his mission to monitor the isolated underground society. For over a decade, Marcerine served as Ping Wing’s guardian after he was orphaned, teaching him magic in secret despite the kingdom’s strict anti-magic laws.
To maintain their cover, Marcerine and Ping Wing operated a liquor business in Coredeep, with Marcerine frequently indulging in her own product. She used this front to hide their illegal magical practice while preparing for their eventual escape to the surface world. Despite her pragmatic intelligence and magical expertise, Marcerine preferred to avoid direct danger when possible, often remaining behind during dungeon expeditions unless the party specifically begged for her assistance. She’s got a notably flat affect, though she sometimes plays this up to express exasperation with Ping Wing’s reckless shenanigens.
She maintains a private hobby of writing romantic fiction that she kept carefully hidden from her companions. Marcerene prefers to stay on the ship away from combat so she can brew potions.
Exploits
Marcerine initiated the escape from the Marrow Kingdom by planning the expedition to the surface alongside Ping Wing. She guided the group through the dangerous Maw of Innocence cave system and participated in their infiltration of the royal castle. After their successful escape, she continued as a core member of the Sock Pirates throughout their adventures on the floating islands of Mercy.
During the conflict with the Swamp Pirates, Marcerine was captured when the pirates raided Eden village and enslaved the local population. She was subsequently forced to become a Swamp Pirate officer and underwent mental alteration through the interference of the villains Jinx and Misty.
Following the defeat of the Swamp Pirates, Marcerine retired from adventuring with Early Rise to assist with rebuilding efforts on Mercy under the administration of Governor Gummo.
