So one thing thats always bugged (heh) me and a lot of other people in the HK fandom is how Ghost and Hollow (and all of the vessels) are the same age yet Ghost looks like a babie and Hollow looks like an adult
here’s my small 2 cent theory why that might be based off of some magic from an entirely different story
one of the first books that I ever read was Eragon, which if you haven’t read it is a young adult book where a teenager named Eragon finds a dragon egg and then sets off into the world with a babie blue dragon (and with his dad that he didn’t know was his dad) to kill the tyrant king who has his own big badass black dragon.
One of the characters that Eragon meets is Murtagh who ends up getting kidnapped in the second book, Eldest, and then turned into a weapon by the tyrant king because one of the dragon eggs that the king has hatches for Murtagh (the egg won’t hatch if its rider isn’t near)
What ends up happening is that in Eragon and Murtagh’s reunion they have an aerial battle that Eragon wins because Saphira (Eragon’s dragon) is much older than Thorn (Murtagh’s dragon)
but in their second battle, Thorn is unusally larger. Almost Saphira’s size and large for a dragon his age. This is because the tyrant king enhanced Thorn’s growth via magic and thus making Thorn and Murtagh a threat much faster
TL;DR: Tyrant king made rival dragon grow faster through magic so that the protagonist would be foiled
what im saying is that PK could’ve enhanced and sped up Hollow’s growth through spells and magic to make them a more resilient and viable vessel even though they are the same age as Ghost.
