Regals are chosen and sent by king's council members. So I think small/fragile regals are one of their ways to control the future kings. Like abused lonely princes let down their guard easily when they are approached by short,thin regals. And those regals don't have strength/power to protect princes from queen or king's abuse.
So, basically, these manipulation has been going for many generations now.
The Council will drug the queen to abuse the young prince and drug the king and control them with puppet regas that looks similar to their fated regas.
When the young prince isolated, with no one to trust, council will send different type of regas to him.
And when he found his regas, start to imprint and depend on this regas, the council will kill that regas.
And then, the council will collect similar looking regas to teach and control to send to the young prince while feeding the prince with the drug/poison to start controlling the prince.
Once the prince is come of age, and fully under control, they will kill the king, and place the prince on the throne to be a new puppet king.
.......
Rinse and repeat.
Cried when Buff dad Abel died (still crying now ╥﹏╥) but lowkey LOve the Reincarnation arc it’s a nice touch to continue the story. What I don’t love is how small and meek they made Abel. I mean the prince gets a glow up of becoming Beefy while Abel is portrayed as weak. Makes me sad but it’s great that they keep his goofy personality.
Also maybe this is just me but has anyone noticed how the regals or dragon tamers are portrayed as a smaller childish boys?! I mean it freaked me out during the first couple half chapters… especially during the king scene and also during the red hair &brown (or goldish eyes) dude who’s on the kings council. I mean it’s obvi fiction but it gave me major pedo vibes, which grossed me. So watching Abel the adult father figure Regis/ dragon tamer help the young prince was so precious. I wished they continue with that storyline to be honest. But let’s see how the story continues!
