In Game Description
A stone radiant with the light of Souls.
The color of the light changes according to the Souls in the area.
It was made by Geri, a friend of Sage Freke, who is known for his magical crafts.
Since it's light and easy to handle, it is widely used by travellers.
The player starts the game with this item by default.
The Augite of Souls is worn on the waist and illuminates the area around the player.
It isn't really a key, but it does appear in the key section of the player inventory.
