Curse of the Riven Sky

It has been months, perhaps a year or two since you have all starting travelling together, and sharing in quests. There have been good times, and bad, but you have come to rely on each other, and your skills. Your names have also spread throughout parts of Golarion where people seek you all for tasks that wouldn't be entrusted to just any adventurer.

You have recently finished one such quest. First what seemed a lowly group of bandits, only to find it had been run by a dragon, using dispensable soldiers to help build it's horde. Among the other goods in its horde which you sold, or kept, you found a book, inscribed with the runes for the word Titan in the cover.

Your detection magics let you know there is power, or some kind inside, but it seems to be locked behind a ritual. Asking around other mages have not been able to help much but ascertained it must be performed by one with cloud giant blood, as it was such who wrote the book in the first place. You have been directed towards a cloud giant called Zoarth. Unlike most of giantkind, Zoarth is not automatically hostile to the smaller races, although he does like his privacy. His castle lies at the top of a high peak in the Kodar Mountains.

Finally you have found yourself at the bottom a path said to lead you up Mount Kallaris, to Zoarth's castle. Looking up you can see the mountain peak is shrouded in clouds.
