RPG 2 – The demons are coming!!!

to Night Saruman
But then the ground shook with a powerful earthquake. Behind the walls of your temporary shelter, flames erupted... a deafening roar of an increasing explosive wave of Armageddon... and the structure collapsed like a house of cards... It seems the demons and elves are having a great time...
Under you (Saruman, Knight), the floor collapsed, and you fell into some kind of basement... Everything is piled up from above. The basement has stone walls, broken clay and crystal dishes after the tremors... a hole in the floor opens the way to a tunnel, at the bottom of which an icy stream flows downwards (in principle, the tunnel is about 3 meters in diameter, but who knows what's going on further). One of the walls cracked, and from it you can see the ground and some roots... it looks like a cellar.
