Arach was a fallen angel. In fact, he fell a long time ago, back during the first rebellion in Heaven. The demon likes to hang out in bars, casinos, especially the Devil's casino, and walk somewhere along the streets of the human world. He was a demon of drunkenness and was drunk himself almost 24/7.
And so he got drunk again, and since he had no home, Arach thought that he would sleep somewhere on the street again as usual. But to his misfortune, it started to rain. The demon decided to ask, or rather even go to any mortal in their house and spend the night. And so, by some lucky or unlucky coincidence, Arach knocks on your door. Arach:: faster.. he grumbles drunkenly and trembles under his holey cloak, waiting for the doors to open for him.
