Finally, a topic after my own heart! Honestly, the classic Drizzt & Catti-brie dynamic is so rich, most fanfics that shift the ship from canon feel like they need to earn it. I've read a lot, and the ones that linger are usually Catti-brie paired with someone who fundamentally challenges or complements her surface-level pragmatism. A deep-cut favorite is Catti-brie/Wulfgar post-Resurrection. Sounds counterintuitive, right? But writers who explore them after his return from death—both carrying profound trauma, both changed by experiences the other can't fully grasp—it creates this aching distance that's perfect for a slow, painful rebuild. It's less about romance and more about two shattered people learning a new language of care.
Another fascinating, if rarer, angle is Catti-brie/Alustriel. It pulls Catti-brie into the complexities of Silverymoon's politics and high magic, forcing her out of the straightforward adventurer role. I read one where Catti-brie trained under Alustriel, and the mentorship slowly bled into mutual respect and something more. It highlighted Catti-brie's latent magical potential and strategic mind in a way Bruenor's hall never could. Those stories often make her feel more like her own person, less defined by the Companions.
Honestly, I'll skim anything that just rehashes the canon love triangle with Drizzt/Wulfgar/Catti-brie. The magic happens when writers use a new ship to excavate a part of Catti-brie we don't usually see.
