BBC Merlin but everybody lives and they get to the golden age and year by year Merlin does more and more magic. Sure, simple stuff that he grows more comfortable doing, but then he starts building protective wards around the kingdom, or heating water throughout the castle. Anyways- consistent background magic, and over time his eyes grow more and more gold.
Five years into it and Arthur realizes there's golden specks in Merlin's eyes that don't go away. Ten years into it, he can't remember the last time Merlin's eyes weren't gold.
Idk just representation of Merlin's power as the background magic flows through him with such ease, as well as proof of how much of himself he gives away for the prosperity of Camelot.
