I was playing as a cynical self-interested Warlock. As she tried to read my mind I came up with the idea to lead her to the Grove in hopes of laying a trap for her as a way of getting rid of her. I was foolishly thinking she would show up with a similar raiding force as the first battle of the Grove. When I saw her army I figured I was screwed (was really my first playthrough and I was still sucking at combat) so I turned on Zevlor. The ensuing battle was a blur as I had no idea the game could handle that many individual fighting characters. When it was done and I met up with her I was completely taken in by the power of her personality. I then decided my character would go completely in for her and the Absolute (Paris is worth a mass!) and the resulting celebration party and evening encounter was a surprise that blew me away from a story point of view. I was definitely hooked on the game then.
Since then I have many different playthroughs running the gamut of good, neutral and evil, different party compositions and numbers etc, so much variety.
