Restore blueprint rewards for exploration

Something that the game Once Human has which encouraged exploration, even though the locations were basically cut and paste, was that each of the bigger locations had a specific gear blueprint you could obtain.

There was something similar in early Nightingale, where completing a Bastille would get you a tech tree unlock.

What could be done is fey bastilles might have fey-only items, and you can deconstruct these items for research in order to learn fey fashion or fey technology. Once you have enough research accumulated, the fey tech is unlocked.

For example, instead of Realm Cards being so easy to get compared to their useful and interesting effects, maybe this could be an alternate way to earn them.
Or the player could learn how to make a fey style sword or sniping rifle or energy weapon, something already used by one of the enemy types.

Similarly, settlements could have building or supply quests in exchange for housing blueprints or technology unlocks or fashion unlocks.
