"The earliest days of #EnigMarch" would be the 2022 prompts, which I wrote puzzles for in June or July of 2023. Here are those puzzles. The day 6 prompt was "Island," and my puzzle was a sort of word search on an 8x12 grid just like the one we see in this puzzle.
Overlay this grid on that grid and take out the indicated letters in the indicated order to get the ansewr, ROMANS. I wanted to do something more interesting with this idea... but I didn't!
