Took a few mins, but managed to get the credits mostly deciphered.
As one can see, the vast majority are fairly well known planets (and two hyperlanes) some specifically relevant, others not so much (yet?), or have simply featured in Rebels and/or Clone Wars. The rest are the three new planets introduced in these episodes (Arcana, Seatos & Peridea) plus three others I can't place. "Odyn" seems like a fairly obvious reference to all the Norse & Celtic lore references on display. While the other two are a little tricky since the "I" "N" runes are rather similar, and hard to distinguish when they're distorted and/or show from oblique angles. Also that there was one rune I couldn't place with any of the eight unused letters. Presumably these odd ones out will show up later down the line.
Yavin is a curious inclusion given the role ancient ruins are playing in this show so far. Perhaps we'll be getting some Massassi connection? But it did feature in Rebels, so perhaps that's all there is to it.
I noticed this new rune script (Dathomirian?) also appears at both ruin sites and in the holomap, so I'll go back and have a look at deciphering those later when I have some spare time.
