HMMM maybe a lot of the stuff that he missed out on or literally slept through. He's eons old so in some way, even asleep, I want to figure out if he could have experienced the Allagan Empire, the Calamites, older history like that... at least artwise I'd like to draw little scenes or vignettes of areas around Eorzea and beyond Catman has camped and travelled through?
I've got vague ideas for a Lightwarden manifestation if that were to happen to him as well...
