Hello,

I can't remember this game: it starts with a male protagonist who has a nightmare where a dragon kills his sister. Then he wakes up in the shed with his sister on top, waking him up - they are not in a sexual relationship (yet?).
I remember there's an abusive (step?) father, a drunkard ex-knight who would train our male protagonist later, a closed down temple with some weird nuns I guess.
Later in the game the siblings get split up and you are able to chose which character you play.

You can point and click on the map, move the characters, gather things, fight, etc, so it's not a visual novel.
I hope someone can point me to this game.

Thanks.
