A prayer to Corwin? Well, I offer the extended cut of one used by the first worshiper, Chip:
O Mighty One, O Mecha Maestro, O Corwin of the Raven Hair, Ruler of All that Clanks and Kicks Ass, I could really use some help right now. Actually, it's either you or my Dad, and Dad would crater the place in the process. Anyway, if you could kindly come here in the next (insert time here), I'd really appreciate it. And yes, I've done the math twice. Okay, three times, but it's amazing how fast the mind works when you're running for your life. Sincerely, your first worshiper, Charles Philip Mui.
(I'm sorry, I couldn't resist.) :-)
