Two Worlds: Epic Edition (2009)

At the beginning of your epic adventure, a mercenary task takes you to the far north - but you're also following up a mysterious lead at the same time - the first clue you've been given since Kyra's disappearance. You get a shock during a meeting with the delegates of a dark Brotherhood - your sister's kidnappers are indeed after your family's relict. Whether there's any truth in your family being chosen ones or not, the others obviously believe it - and if you ever want to see Kyra alive again, you'll have to act swiftly...
