The original story of Themeire was a "Cult of Talimar" traveled to "the new world" (read; similar to our world's east coast USA), and tried to summon Talimar in the colonies. That ghost chasing you (Talimar's mother) would have come over on a ship, Dracula style.
As for The Uninvited 2; sadly, it won't com out this year, as the various team members, myself included, are currently fulfilling other contract with other studios. That's also why we didn't make a KickStarter, so we wouldn't be obligated to work on U2 just yet. Once we're done all of our respective jobs elsewhere, we're going to reconvene and work on U2
