So, if you were an ancient, evil demon seeking to betray the careful, suspicious, not haughty-stupid god who released you from imprisonment (so it could learn some of your sorcerous secrets), how would you go about doing this, assuming you had no more power than a mortal?

I'm trying to work through this idea and hitting a block. I might ultimately reject this idea altogether and cobble something else together, but I'm curious what clever bits you all can come up with.

RULES: Anything goes here, you fill in the details of anything and everything beyond the above (I'm looking for inspirational ideas, not my story being written for me). That also means it doesn't need to be polished fiction, either: snippets of dialog, half-formed ideas, and straight answers are all acceptable as well as little fiction bits.

Also, if this has a decent response, I might do this around once a month or so, just to get everyone's creative juices flowing and see what we can all come up with and just have some fun.

WHY? I've been pounding out chapters of "The Children of Uru" -- my NaNoWriMo submission last year -- to bring a close to the story. Though the main plot has been more-or-less solidified from the start, I've hit a few blocks here and there over the last few months regarding how the story would progress in the details of each event and thankfully overcome each in time. This time around, I decided to try and tap the community for some inspiration, so I can take a look at it all from other angles, rather than what might be a self-imposed rut.
