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, death 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.
