quote Hellgate Guru

...fun about the game is that there are not only rare items but also rare quests and rare monsters. So the chance exists that when entering a certain level you get a message on your PDA. A wounded Templar asks for your help to finish the quest he is working on. The chance that this Templar appears on your PDA is fairly small, so the surprise is all the larger (and all the more fun) when during a mission you encounter something that almost no one else has. Fun to brag about to your friends. Flagship tries to guarantee you a unique as possible experience with this and though I didn't encounter this rare quest myself, I think it's a great idea.
