I finally got all 3 endings. The hardest was Lora's ending. There was not really a direct path to it. No obvious choices. A lot of trial and error there.
A real pity though. I love the story line. But as it only has 3 endings I was disappointed.
Now I would like to know how to finish all the quests. I wan't to do that before I start on part 2. I bought the bundle last night.
