I'm about to begin running Iron Gods, with the first session two days from now. To that end, I'm soliciting ideas on wags of foreshadowing Unity's end goal and bringing more to the forefront the fact that Ozmyn Zaidow is a puppet of Unity, neither of which are made very explicit in the adventure itself, as opposed to DM knowledge.
I recall seeing someone post an idea about the Technic League constructing broadcast towers to carry Unity's signal, for example. Perhaps Zaidow might be conducting experiments in cybernetic brainwashing, and have some programmed fanatics as guards. Probably Zaidow and perhaps a handful of other League Captains should have holy symbols of Unity.
What are your suggestions?
