so, i think i've mentioned this previously, but one product of my setting's ancient dragons that persists to the galaxy's modern day is that most beings formed of magic take the shape of dragons
but this doesn't just extend to beings formed entirely through magic. beings that become more magic than physical tend to become more draconic as a result.
so for example, Erick, if he's got enough of the seals he keeps on his magic broken, starts taking on a dragon-like aspect, flowing with countless enchantments to keep himself stable
