I like it, a lot. I only recently started playing a bit of Tomb of Xinroch and I gotta say, it doesn't make any sense at all that the necromancer in prison asks for the encrypted scroll. Specially since the story he tells you has absolutely nothing to do with it. It's just a cheap excuse to make you unable to enter the gloomy cave when going for the tomb. Also, it's weird that there's a whole lot of guards around the tomb, still you can enter it unchallenged? Furthermore, the "high lady" of the dark knights being female is really weird. It comes up to me as forced, trying to be politically correct and give women more important roles, which doesn't fit with the spirit of the game. Same with the lady in Attnam with a thunder hammer.
Also, there's no hint whatsoever that you can give the scroll to someone else. The game points directly at giving the scroll to Petrus, it's the first quest and it's pretty straightforward. Honestly, I'd like an expansion through the blue portal in Oree's room.
