How is the Lia Fáil (the Stone of Destiny that proclaims kings) reimagined into Lia Dàn in The Destiny Cycle?

Pronounced Lia Dawn, the Stone of Destiny is one of three Tuatha relics that the Dark Goddess weaves into the Triple Dàns. Lia Dàn governs the Celtic Cycle of Time. Except for Danu, who brought Lia Dàn from their Atlantian origins, the Tuatha Gods or Goddesses must touch the Stone of Destiny to travel through time in any direction. When Breanna wields the Triple Dàns to change her timeline, she also no longer needs to touch the Stone of Destiny to travel through time.
