If the game only canonically takes place within a few months and the portal to Mareth opens only once a year does that mean we will not get the chance to rescue Calla?
Pretty much all we know about Calla is that Savin has Reasons for vetoing dreams involving her in Mareth (even inaccurate ones) and that we won't be going there.
