L. is the Sage of Mischief magic, and more than a little playful. Though she does have a mean streak, it tends to remain on the down-low, so to say. She's also extremely intelligent, though usually pretends otherwise, because it is much better and easier for her to work when others underestimate her.
Despite how it looks, she and the other two sages are good friends. Though Morgyn is newer to this whole thing than she and Simeon are, L. sees Morgyn as if he were her own child, though she'd never say as much because Morgyn adopted Aine, much to his own detriment. L. would never say anything bad about Aine, but L. had her reservations about her. In any case, L. is not an offensively powerful spellcaster. Her mentor was a shaman, and L. follows similar trends, coaxing magic into doing as she desires rather than forcing it to bend to her will as untamed mages do, but this leaves her notably weaker because she will not just take what she wants.
L. works best in the shadows. She prefers to work alone, as well, and often does things that make no sense in the moment, but make sense later as her plans finally bloom. She's a slow starter, in that way, but once her traps have sprung and her magic has unfolded, you have very little chance of countering it or escaping.
