Corbenic is a place of marvels, including, at various times, a maiden trapped in a magically boiling cauldron, a dragon, and a room where arrows assail any who try to spend the night there. These wonders cause Sir Bors to name it the Castle Adventurous, "for here be many strange adventures" (Le Morte d'Arthur, book XI). Yet it can also appear quite ordinary: on an earlier occasion, according to the Lancelot-Grail, the same Sir Bors visited without noticing anything unusual. https://en.wikipedia.org/wiki/Corbenic
