Rex slipped away, heading back to the library. He had his own little nook-- one could almost call it a nest-- in a dark corner of the library, on top of where two shelves met. He had cushions up there, as well as a candle for when it was dark. Using a ladder Rex made it up into his nook. If one looked up in the nook, they might be able to see his eyes glowing. It was a phenomenon that was a side effect of his curse.
