Tear of Vendra
From Legonia
The tear of Vendra is a crystal globe with elvish-like insignias and assumed as magical object which holds a big source of Mana. Due to Amazon Mythology, the Godess Vendra lost her only tear in life after Arkando betrayed her and was beatened by the demongods. This tear holds all pain of Vendra's soul and a lot of her godly power. Where this artifact left is unknown but most theories say, Asuria, the amazon queen owns it in her treasures.
Aside the amazones, also many mage communities are after the object, e.g. the druids or Witch circles.
