Don't have to read past half of Glass Sword, although obviously recommended but no spoilers. Mare Barrow and Tiberias Calore(Cal) fanfictions by ME. No one shots. Just multiple stories. Maybe a few Maven/Mare before he turned evil. Maybe some Kilorn/Mare thrown in there bc he's my favorite character. OR WAIT SOME CAL AND KILORN bc i ship *cackles maniacally*
