There are three underground chambers or "rune rooms" around Loc Muinne. Each room has a warded chest protected by one of twenty-four possible combinations of four runes on the wall or floor: animal rune, art rune, sky rune and time rune. In each room there will also be a page with a written hint for the correct order to extinguish the runes (see below). Extinguish the runes in the correct order and the chest will open. If you extinguish the runes incorrectly, you'll either get burned, shocked, or poisoned. You can cast Quen to absorb the damage.
You will need to buy the Runes of Power series of books to decrypt the magical signs and hints in the rooms as part of the quest The Gargoyle Contract.
Upon deactivation of each seal, part of the following is heard:
- You hold the sword of Aramil, who defied his king's rule. The Lord of the Wild Hunt desires the gene of the Elder Blood. He seeks to fling open the gates between the worlds, so that terror and destruction may reign. The King of the Hunt ordered me slain, and the wraiths born of his command assumed living form, pursuing me through the voids between the worlds for centuries. I have arrived at Loc Muinne. Though tired, I know I will not rest. The riders of the Hunt draw near. On my back I can feel their deathly breath.
Then once the seals in all three rooms have been activated, return to Bras of Ban Ard for reward of 200 
and 150 XP.
