Solis is the Shahiid of Songs, trainer of the Red Church acolytes in the art of steel. Mia Corvere cut his face during their first sparring session. Solis hacked off her arm in retaliation. That said, the two harbor great enmity for one another.

This only increased when Solis was appointed Revered Father of the Red Church and head of the Church Ministry, the man responsible for dictating the targets and lives of the Church Blades of Our Lady of Blessed Murder, Mia included. Although traditionally the Ministry would select a new Shahiid to fill the position vacated by the new Revered Mother/Father, because of the current state of the Church, vastly depleted in both resources and acolytes, Solis has remained Shahiid of Songs and continues to train Church acolytes despite his promotion.
