The Regi Stone is the heaviest stone in Satisfy.
Information[]
Regi Stone is a mineral and stone, Grid got to know about it when he glimpsed Antrino's Dictionary of Minerals.
According to Grid, it is a mineral with little value. Weight is directly related to hardness. This directly means that this mineral's density is very high. A piece the size of a fingernail is at least 60 to 80 kilograms. It would be ineffective to make something using the regi stone. The shape wouldn’t change no matter how hard a person beat it with a hammer. Grid despite being a Legendary Blacksmith and Pagma's Descendant thinks - it would take him a few months to just smelt the Regi Stone. And for a Craftsman it might take years, or perhaps even decades.[1]
Pandemonium of Dwarf Kingdom[]
The door of Pandemonium of Dwarf Kingdom in Talima is made up of Regi Stone. That's why normal people, except Dwarf Royal Family, can't open the door. However, Grid proved Antrino and other Dwarves wrong by opening the door with the power of Great Demon Saleos-Power of Not Knowing Defeat which had been absorbed in the Rune of Gluttony when he defeated Saleos.[2]
