Hello, at some point in the game you have to kill him, when you goto the lower levels and he chases you through, when you get to the end of it, you get blocked off, all you have to do is block or dodge his spells and break the jars

u cant kill him normally u have to lead him to a certain room through the cellar and then break pots in the room and he takes damage i am also on lyron and i cant find one of the pots at a certain point so it gets even harder

nevermind i figured out that you dont need to kill him at all =/

When you get to lyan's tomb chamber (Ossurary) You will have to listen to him talk or bypass this by pressing the start button. He will start by throwing things at you. Block these as best you can. The primary thing you need to too is break the WHITE URNS. Start with the one on the table, then the two to the right. Once this is done a force field will drop to one of the rooms keep breaking the urns until the center room containing alot of urns opens go in there and break the urns until you hit the one containing his hand, at this point you have won. Make sure you go through all the little nook and grannies, weapon racks, and treasure chest. You will find a secret door now open to the rear of where you started by the table. Take this up to the next floor. Treasure chests and weapon racks there too. Go to the obsevation room now, it will now open since you have lyan's hand.
