[@Stern Algorithm] I'm not a GM obviously, but I'll share some info I have involving Inhumans in canon Marvel.

1. If a normal-looking Inhuman woman, for example, marries a normal man, is there a possibility that their child is born as a monstrous inhuman? I know there are genetic 'castes' among the inhumans and I wasn't sure if monstrous deformities could come from the offspring of 'purer' lineages.

Marvel seems to define Inhunan Hybrids as either the offspring of a single Inhuman parent and those with Inhuman lineage (ancestors, uncles, grandparents, etc.). The [i]vast majority[/i] that I have [i]briefly[/i] looked at appear human after being exposed to the mists. Luna Maximoff, Daisy Johnson/Quake and Kamala Khan/Ms Marvel are good examples of this. But, there are [i]a few[/i] that appear less human such as [url=https://marvel.fandom.com/wiki/Gordon_Nobili_(Earth-616)]Gordon Nobili/Lineage[/url].
