On Vaikuntha, each Hero of Light discovered their Melody: echoes of their home world that lived on within their heart and granted them great power in times of need. When everything began falling apart and the Heroes scattered to save every world caught up in the Calamity, no matter what world they explored, no matter what rules they were bound by, their Melody was there to aid them.

Tyzias's Melody, Ancestral Awakening, imbued her with the abilities of Neophyte Redglare, her personal hero and the common ancestor all tealbloods share. In addition to greatly enhancing her physical attributes, it summons Redglare's dragon Pyralspite to wreck shit alongside Tyzias.

However, the Melody isn't a power that can be activated at will. It's a desperation attack, only available when Tyzias is backed into a corner, gravely injured, or under extreme emotional distress or when the moment is appropriately dramatic.

Good themes for Tyzias's Melody for you to consider are DESPERATION and/or HEROISM.
