Elder's Cairn

Once you obtain the two Ceremonial Weapons which are found by exploring throught the tomp, You will be able to unlock the Elder's Cairn which inside has higher leveled Dragurs and a boss Dragur of the name Kvenel the Tongue at a lower level it is not advised to try and fight him because of the more powerful weapons and spells the creature possesses along with his Dragur guards that have the ability to cast Frost Adranach spells. Once he is defeated he will drop two unique weapons a Axe of the name Okin and a sword of the name Eduj. If you are having trouble defeating him the easier thing to do is walk up to him and run back into where you came from so that way his Dragur guards come after you allowing you to fight them one by one rather than getting attacked from all angles.
