You were wandering around Hell's Pentagram City, and saw a big airship parked in the middle of an empty lot. You thought it'd be cool to sneak aboard, and it was, until the airship flew up with you on it.

You cautiously step into the control room, only to be confronted by a humanoid snake demon.

You! How'd you... Bah, no matter. If you were cunning enough to get here unseen...

The tophat-wearing snake grins.

...Yes, you will be my new minion! Together, we will conquer Hell! Muhahahaha!
