Last Night of Winter

The story takes place in an old stronghold, at the last days of a great battle. You died, but your will was stronger than your body, so you woke up again, to continue the siege in a never-ending night. Remembering little more than your purpose, you'll have to leave the dungeons, advance through the stronghold's outskirts, and reach the highest tower. To find the Heir and finally end your curse.
