I think I was originally working with a word count and either cut or forgot about incursion specific drives, whoops!
I'd say "seek the engine" or even just "survive" work as solid universal drives, or reinterpreting regular Gold drives, or extrapolating a drive based on the background + occupation combo would all work!
Hope the sessions go well, and feel free to drop me a line about any other questions (though it was been a minute since I've done anything Trophy hahaha).
