You start with Knighthood. (Permanently Upgrade a character.)
Gwen is one of the advanced Heroes in Storybook Brawl.
Unusually, Gwen’s ability is a one-shot: she starts with a free Spell that can be used at any time but only once. That spell is Knighthood, which normally costs 12 Gold and allows you to permanently upgrade a Character. That’s a powerful bonus, the difficulty is deciding when to use it. If you use it early on a low level character, it’s a bit of a waste. But if you try waiting too long, you might not survive.
