The Library is an area of Dracula's Castle. Its 2 Mirrors of Life are in the Rhetoric Shelves and the Exhibition Room, and the Ferryman's Wharf is in the Bridge of Knowledge. Carmilla is fought in the Observatory, with the Exhibition Room as the nearest Mirror of Life. Defeating Carmilla gives The Occultist and Blood Spikes.
Chests hold the relics Midnight Tear and Lich's Mark in the Rhetoric Shelves, Revenant's Shard in the Curiosity Cabinet and Wraith's Tear in the Study Room. Weapons include Fleuret and Tower Shield in the Condemned Shelves, Thorn Whip in the Fine Arts Shelves and Durandal in Lisa's Laboratory. Brauner's Paintbrush, a Keepsake, is in the Observatory, and Aerial Rush comes with the Arcana of Brauner in the Observation Tower. Pick up 3 Brave Heart Fragments and 3 Wise Heart Fragments; 4 fragments make one upgrade of 20. There are 9 XP statues worth 300 XP each and 26 Secret Areas.
Exits lead to the Main Hall from the Bridge of Knowledge and to the Clock Tower from the Forgotten Bridge. Clues for The Occultist are Blood Poem, Magical Brush, Organic Astrology and Star Chart. Expect skeleton archers, flying skulls, spear guards and werewolves.
