How involved were the pale king and white lady in the raising of the vessels? Did they offload all the training to the warriors, or were they personally monitoring every vessel's development?
Pretty involved! The king, at least. And, well, mostly in the beginning.
The retinue handled a lot of the general care, but the king actually spent a lot of time with his children when they were young beyond just training. Though notably, he spent a disproportionate amount of it with his first born over the others, a problem that became worse over time. The queen? Eh, not so much. She never bought that whole "overpowering the Radiance" business and had no interest in becoming attached to offspring she considered marked for death.
... They didn't see eye to eye on the other's choices.
As for combat training, the Five Great Knights were primarily in charge of it, supervised closely by the king. By the end of their adolescence, Worthy themself took over leading the routine. You never know what to expect in battle, so it was ensured that the vessels would face plenty of variety. The Great Five would continue to challenge them in every way possible
As the vessels grew in age and strength, warriors of all kinds were invited to test their mettle against them. There were many bugs eager to claim the bragging rights of besting a higher being. Some even managed to claim those rights.
The king watched over their progress less and less as he trusted Worthy's judgement of theirs and their siblings' abilities. Although, very rarely, he'd step up to gauge their abilities himself.
I'd love to get more into the relationships between the vessels and their parents because there is a LOT to say, but I think that's a bit outside the scope of this ask. We can definitely talk about it later :]
