The eight item to be auctioned was an item called a Runeforge Stone.
When Calista introduced the Runeforge Stone, the Auction Hall was silent not because of shock or disbelief, but from a lack of knowledge as to what a Runeforge Stone was.
Only a select few knew what a Runeforge Stone was, and their expressions were relatively mild despite knowing how rare a Runeforge Stone was and the purpose of a Runeforge Stone.
Those who had no idea as to what a Runeforge Stone was had curious expressions as they waited for Calista to explain what a Runeforge Stone was.
A Runeforge Stone is basically a stone that has being filled with a condensed mass of pure rune essence that's naturally formed in places where universal or world laws converge. It can be ancient battlefields of rune-wielders, collapsed dimensions, and even the corpses of extremely powerful beasts that utilize runes in battle.
