My Sylvari Ranger's Personal Story presented me with the first moral dilemma I've come across in this game.
After working to help a fellow Sylvari track down his kidnapped love, she refuses to be rescued. She has fallen under the spell of The Nightmare Court and no longer wants to return home.
Her love Tiachren still believes in her, and wants to rescue her. She is leading an assault on a small village.
Your choice is to go and help the villagers defend against the Nightmare Court, or go with Tiachren to try once more to pry her from the grasp of evil.
You are warned by your mentor Caithe that no one escapes the Nightmare, and that Tiachren will only be drawn in. She is so cold and unfeeling, though (luckily your character sees that and calls her on it) that she doesn't seem quite trustworthy.
I just tortured over this. I had been fighting at Tiachren's side through several scenarios, and I liked and respected him. Love conquers all, so I do generally believe. My best instincts said go help him.
I couldn't let a village of innocents die though, particularly if he also fell to the darkness, which seemed the most likely outcome given what I knew.
So I chose to help the village, and there he was, a being of darkness at his love's side and I had to defeat both of them.
As it turns out, there isn't a different end to the story whichever choice you make. You're a hero and the "Pale Tree" is all proud of you.
I don't know if the game has things down the line that result differently from this, but I hope it does.
