Ruby Sunstone

The Ruby Sunstone is a mysterious dark item, capable of summoning evil forces, including dinosaurs, while at the same time boosting the current possessor's strenght and power. It also serves as the "key" to open Ogthar's sarcophagus, to whom he was previously imprisoned from within. It appears as the prime weapon of the animated film, Dinotopia: Quest for the Ruby Sunstone.
