Never seen any if those , but maybe for a plot a revolution trying to stop another revolution, while both are trying to stay under government/monarch/dictator radar? I was actually throwing around ideas for an essay myself earlier today, just was the first thing that came to mind. As for technology/weapon/etc., hmm... Mayhap a quick mind for a source of power? As you can draw power from brain waves, a bit far fetched and sci-fi-y I suppose. I'm coming up with useless garbage here, bleh. Brain-block. .-. Anyways, good luck on your essay.
Make a story about destiny crystals -> certain people are born with them -> if someone with one kills someone also possessing one they get that persons "power"(could be single things) —> bad guy figures out and starts doing so —> protagonists friend gets killed and he sets off to find antagonist —> throw in a few friends on the way -> miniboss fight -> treasure —> dramatic final battle
