With the Rock Key...
It took me forever to find the guy that was looking for the Rock Key after I found it (he's in Keops, btw). Now that I activated the quest to give him the key, it won't let me hand it over to him!?! I was expecting something kinda cool...maybe some expensive items or something nice, but nothing can happen if he won't take it...
Otherwise it was a pretty well made, addictive, old-school RPG and I liked it (I stayed up past 6 AM to finish it). It reminded me of Shining Force for the Genesis. 5/5, 9/10
