Odine studied her and find her special and Adel changed her plan.
Ah ok, so basicaly Adel was engaged in a common practice of searching for a succesor, and thats how Elones powers were discovered initialy.Adel became interested in Elones powers of time travel.

Later on Ultemecia put her conciousness into Adel in order to carry out her own plans, after wich Adel was imprisoned. Is that kinda sorta what your saying?
