On this page, we discover a mage arriving at a stone monolith in the middle of a snowstorm. Using magic, the spellcaster unearths the Prehistoric Vow from the stone. How the mage knew a sword would be there is unknown, but upon further inspection, the mage is carrying an empty sheath, which could be hinting at the fact that the sword belongs to this figure, who hid it there for unknown reasons. Alternatively, the spellcaster could have been informed of the blade's presence, and simply came prepared.
Another theory is that tha Prehistoric Vow is a sword crafted only for that man. The man knows the location, how to get it and the right spell to extract it.The purpose of that sword is a mystery.
