Let's see the Dracthyr story so far:
- Nelharion a giant fuckoff city-sized dragon figured that he needs an army of skinny human sized boys to fight in his army.
- The other aspects were totally cool with infusing soldiers only loyal to Neltharion himself, with their powers, for some reason.
- Despite their single-minded loyalty the dracthyr were controlled via a titan artifact with worse signal range than an average wi-fi hotspot
- In a battle where the titan wifi was present it got damaged so the dracthyr became self-aware and free to blindly follow Neltharion and question everyone else.
- Since the titan artifact is unreplaceable somehow instead of killing the army they decided to lock them up in stasis with an army of blue dragons staying there as guards.
- A failure in the stasis system can totally kill dracthyr but there was apparently no plan to implement this to get rid of the dracthyr problem for good.
- When the Primalists attacked the Forbidden reach, the blue dragons didn't pull a Maiev and instead decided to kill all the dracthyr who conveniently woke up. Also they totally didn't get the memo that Malygos has been dead since Wrath so no point in following his orders.
- The dracthyr kicked blue dragon butt because apparently they weren't created with a failsafe against hurting titan creations. Go figure.
- When two black dragons arrived they immediately asked what's up with Neltharion because they are still totally willing to follow him without titan mind control. But only him, not the two new guys.
- After learning about the past 10 thousand years they just shrugged and decided that they need to find a new path. No existencial dread, no trauma, or drama. Just: guess we are free.
