With mockeries running amok wouldn't it be more accurate to say this is for Electric Bastionland? I don't remember any mention of mockeries in Into the Odd.

There's barely any setting in Into the Odd, but it's the same city as Electric Bastionland, just a couple centuries earlier. Why wouldn't there be mockeries?
The games being so similar, you could certainly run it in either (or Cairn, for that matter). But I had the character packages in Into the Odd in mind when I wrote some of the bits, and I use the pennies, shillings, guilders currency system from that game as well.
