A central theme of my stories is the using of a powerful artifact, the Gift of the Gods. The Gift of the Gods is actually four parts, (two gems, a staff and a circlet), but a strong magic user has to use the magic to make it work. Though presented to the High King, who did learn magic to use the staff, a very strong magic user must use the Gift. The only people to use the Gift was Amber Blackwolf and in my High King's Sword, Duncan. Both were very gifted magic users and could take the surge of magic running through them to call upon the Gods themselves.
The staff originally called eight dragons to open the gate, but these dragons came from the Chosen, breaking a part of their souls off to create them. Only Flash was the only flesh and blood dragon to be dragged into the mess. The second time the Gift was used, the dragons created by the Gift were used once more.
To use the Gift, the mage must be in the Temple of the Gods chanting the incantation which is in Ancient Elven, his hand around the staff, the circlet upon his head. The power surging through the user most likely will kill them, unless the Gods intervene and find the person worthy.
