I come to, alone, in the Fade - the realm of demons and spirits. The first ones disguised themselves as other Grey Wardens, one taking the form of Duncan himself. After destroying them I find the depressed mage Niall trapped there too. Looks like it's up to me to find a way out and I do so by learning how to shape shift into various forms, unlock secret bonus rooms and defeat mini-bosses. That all sounds very "gamey" but it is all very awesome and a very fun to experience!
Eventually I locate each of my comrades to stir them from their slumber with Quickly being the easiest - I literally just woke him up. Morrigan also knew what was up and was quick to assist in dispeling the demon trapping her. Alistair on the other hand was completely fooled, having a vision of his sister and her children. It wasn't till I destroyed them that he came to - realizing their manipulation and apologizing for his dimwittedness.
Finally it was time for a showdown against the sloth demon (who also had shape shifting abilities) and while he did put up a decent fight, it was he that was ultimately destroyed in the end. Niall then showed up and told us of some scroll he had on his body, and for us to take it to protect us from mind control further up the tower. He had been in the dream too long and could not escape any longer. The rest of us woke up and did as he asked. Before continuing though I did pay my respects to the worldly corpse of the sloth demon, for his realm was super fun and very rewarding. I was a little sad to end him to be honest. :(
But I powered you up!
