Who will solve the riddles?

The Skleeve posted a riddle below under Chops topic about the lights.
Hard to find, so I thought I'd bring it up here.

What's more powerful than God,
more evil than the devil,
rich people want it,
poor people have it,
and if you eat it you will die!

If you solve it, Skleeve promises to teach you how to make
something cool, like a UFO illusion or something.

There was also mention of "Wastelands" which let's me
report that I am now finished with the "Wolves of the Calla".
(... come, come Kamala. Has this coincidence escaped anyone?)

And Mia is on the loose.

I'd sure like to see the books with the pictures in 'em someday.
