You arrived at a old tavern, you see some strange people here, among them a monk who also looks strange, you heard stories about this place so decided to ask him about something, he spoke to you, his face serious and in a creepy voice

"Greetings, brave mortal, Here in the ancient Huyver Forest you find yourself among the sleeping ruins of the Abbey of Capelle van Kaatsheuvel. A long, long time ago, on Friday the 13th of the year 1876, the entire orchestra of the idiosyncratic conductor Joseph Charlatan disappeared here during an international music competition. After a masterful performance of the piece Danse Macabre, the musicians were ruthlessly engulfed by the Unnameable. Evil, which still haunts these parts today - and manifests itself as a monstrous, cat-like creature. Cursed and damned for eternity, the conductor and his orchestra will play the Danse Macabre in the abbey chapel until the end of time. Be on your guard, mortals. And above all, avoid any contact with a seemingly amiable black kitten. The Unnameable is everywhere. And nothing here is what it seems."

Shortly after he vanishes into thin air and you're the only one who had even noticed him
