I searched the forum because I read the answer to this once before. However, I can't seem to find it. So I'll post my question and hopefully get some help with the answer. Where is St. Maddox's grave? I know there's a big ordeal about finding his grave and figuring out why he's buried under the church instead of the elf. Does he even have a grave site? I didn't need to find it to beat the game, so I was just curious.
You can find Mannox's grave in Roseborough, you need to start running to the west just when you enter there... at some moment you'll see a wheel in the floor... keep running until you see a stone vault with a wheel in it. If you talked with Gunther about the discrepancies in the Archaeon, then you'll know the password that opens the vault, and inside you'll find Mannox's Journal and his sword (just a quality sword). Beware when you enter, the followers always pick up the sword and the book, so you may think that isn't there! I hope that helps.
Not quite in Roseborough though, but a short-ish walk along the coast from the town. You won't see it on the local map.
