The room is small and doesn't take much time to search. Besides the alter are skeletal remains, with several broken ribs and a sharp ritual dagger. The small alcove at the far end contains candles, an overturned table, and the remnants of books, their pages reduced to dust. One particular book, however stands out from the rest. It remains intact despite the passing of the centuries. Its cover is cool to the touch, much like the journal you discovered earlier, only these pages are filled with frantic scrawls and dark magical formulas.

This is a spellbook, though what spells it contains will require magical aptitude to decipher
