that's the one I gave to him 😅. I'll have to hunt for more runes, I think, but I appreciate the help!

Since this comment was ~4 months ago, I'm assuming you already got it or dropped the search. But just in case, the second rune is found during the sign puzzle right before the lamp post puzzle. The hint is to turn both signs that say "Secret" so that it follows a direction, one opens a path for a coin and another for a rune.
