On the stone walls flanking the hidden passage, there were not carvings of the Northern Nobility's design, but rather some murals.
These were drawn with some unknown red pigment, using the simplest lines to portray scenes brimming with primal vitality and intense strength.
In these pictures, one could see Frost Giants wielding weapons, a horn, humans, a blizzard...
According to later investigations by court scholars, these murals were a way for the Val Barbarians to record history, and Oliver, being a descendant of the Val Barbarians, knew this well.
Clearly, the murals within the tomb also used this primitive form to record some true story.
"Frost Giants, a horn, blizzards..."
"This is..."
Duke Oliver murmured to himself, as if the story seemed familiar to him.
He continued walking along the hidden passage, eventually arriving at the end, a secluded burial chamber.
Inside, there were no luxurious burial items, only a large horn placed there.
