No one is without scars. Some are on the surface, and fade with time, but others run deep, and may never fully heal. And any number of things can cause those scars to reopen.
Sunrunner's scars run deep, thanks to the strong emotions tied to them, but she manages them well enough. She has to, given she's an officer in the Royal Guard. But when circumstances lead her towards having to face the roots of some of her deepest scars, she might just find herself on the way to healing one of her oldest and deepest ones. Along the way, however, she'll be reminded that the more things change, the more they stay the same.
