Recently I asked this puzzle, for which I will be providing a new hint, but I want to ask the second part
I am the ONLY one standing between ad23dnd anagrammatically. You have to look for the first half of me
as a separate riddle. which was solved partially
the ONLY one standing between 2d and 3d
But I am not sure, if this will be too broad. I think this question is awesome by itself, I was pondering about the vagueness/broadness about it. (It can also be used as a hint for the riddle mentioned, though it seems a little far-fetched)
