I'm still working out what the fundamental scarcity is. I feel like trust and loyalty are the obvious ones but how do I reflect that?
For "fundamental scarcities" to propel threats/fronts look at the kinds of threats that come up in the shows. Many can be grouped into categories like:
Hubris - "We can save them without breaking the Prime Directive."
War - "The Klingons attacked the Denarra colony! We must strike back!"
Corruption - "I assure you Section 31's actions are fully sanctioned..."
Assimilation - "Resistance is futile."
Mystery - "It's life, sir, but not as we know it."
Still trying to think of three more to make it a nice eight like AW... *laugh*
