A slightly different Sindar/Falena question...

[Belle]

Are all the Sindar ruins in Falena tied to the Sun/Dawn/Twilight Rune in some way? Or is it possible for a few to exist that have nothing to do with the Runes?

[Leebot]

All the ones we've seen appear to be tied to the runes, and Lorelai's ending says that she'd explored all the Sindar ruins in Falena. So, there might be some other ruins with no tie to these ruins, but that would imply she explored them before the game. It's possible, but it seems unlikely to me; we know she already spent a fair amount of time in the Dawn and Twilight ruins, and she's only 16 at the beginning of the game, so she'd have to start out very young to have explored some other ruins.
