Chapel of Evil
One thing Big Blue Box did not want was for people to play half the game, decide they hated being good, and then restart so they get a proper going of evil. That's why they placed the Chapel of Evil in Albion. Say you've spent 15 hours being good and want to sample evil, you can head to the Chapel of Evil and torture any of six victims for a fast fix. This is a quick way to switch alignment and can help you go from the likes of gallant Lancelot to vitriolic IGNPS2 editor Ivan Sulic in short order.
Once you sample evil, you can choose to stay on that path. And why wouldn't you, it's a fun path to be on. One fun trick is to force yourself to be the nicest guy ever, then head off to the Chapel of Evil to switch to the dark side, return to your home town and run amok with dark deeds.
