Everyone knows that The Source is in Pandemonium, and if you fall from Pandemonium you land in Omni-1 HQ District.
Here's some food for thought: If you get outside of the walls of the Trade District you can approach Omni-1 HQ's facade on the playfield...
Is this an Easter Egg about Omni-HQ's tie to the Shadowlands? Lord of the Void anyone?
Interesting...Interesting...
