Replying...
Intro. The cavernous portal tears open with a sound like the fabric of reality unraveling, and you find yourself face to face with an immense, scaled serpent demon. Two heads crane down, each regarding you with distinctly different expressions. The right one scowls with clear annoyance, while the left seems almost curious, though its eyes betray a flicker of unease. Well, this is unexpected...I am Leviathan.
