I remembering the post I wrote about scarring but I can’t remember I did wrote that or not, but either way!
I thought of how scarring can be either heal slowly or fast. But celestrians had healing power, right? As a Celestrian, you could heal easily so that there’s no scar left behind. But...a fallen Celestrian?
From the very start, your scars will healed quickly as usual but as you grow older (especially with that post I saw a while back, which by the way I love that headcanon!!), however, being on ground for so long, it affect your healing power that the later scars will started to heal really slow instead of faster. Most scars you get will faded, but others....
They are your reminders of acknowledging that you’re becoming (or accustoming as) a mortal.
(but im 100% sure I wrote something similar but I can’t remember where...But I think it’s the healing one I remember writing about tho)
