Thanks for all your replies so far.
The reason why I created this topic in the first place is because of the objective and supposed choice you have.
The quest objective is 'Decide what to do with Heart of Nagog'. The description says that if you destroy it there might be unforseen consequences and Anjani actually told me it is for the best to leave it alone, which I did.
Seen as I have actually made the choice of leaving it alone, how come the quest is still active? What I'd really like to know is if you can complete this quest and actually not destroy it.
If you read all the books in Gunderic Manor, Anjani actually says it is not a good idea not to destroy it. Seen as the quest objective actually says to decide on what to do, I do not understand why you cannot complete the quest by leaving it alone. It sounds to me like there isn't a choice at all and you HAVE to destroy it.
I'd also like to ask anyone who didn't destroy it whether anything happens afterwards based on your choice of leaving it alone. I'm hoping someone you talk to mentions it and that way the quest ends. It just doesn't make any sense to me that the quest objective says to decide what to do with it yet you cannot seemingly complete quest unless you destroy the damn thing. Crazy.
Cheers,
