Tara told everything that she knew about the secret realm. Though the exchange was only about the information regarding the item that he gave her, she gave a brief explanation about the realm, at least to the point of her knowledge.
The oval-shaped item was made up of Torum Crystal, a very rare crystal even for the ones who created this secret realm. It was used for awakening purposes. Unlike the tools available on Aredia, where there is a chance of failing, it is said to give a person a 100% awakening probability.
The tool is not used to awaken a person but to determine what his talent was before the awakening happens. This helps the people a lot and also reduces the wastage of resources.
