I would love to get Cloud involved! His crystal ties him to Fayren a little even if he resides in Genessia.

Depending on how the plot progresses, Cloud could either be someone who lends his strength to a party that mounts an assault/rescue mission when more is revealed about Winter and her subjects.

Maybe even being part of a group that creates a path for another group to reach the castle and reach Winter. Either way! You'll definitely want Cloud on your side if you're tackling all these snow beasties.
