Currently, the final Windurst quest in WotG is "The Forbidden Path". Who is this about?

Spoiler: show

So is this about Aldo? Or is this about a Zilart or Kuluu character perhaps? Is the reference to the ghost holding the Gleipnir completely unrelated to the rest of what Carby was saying? The ghost was a tonberry, aka a Kuluu.

Thank you!

Edit: NVM, I feel really stupid now. There is no need to answer this thread, and mods may feel free to delete it. Sorry about that.
