Forgotten Memories (PMD Story.)

There was an Abra called Ulli.
She was a member of a team called Team Savior.
One day, Ulli could evolve, but she didn't want to.
Her team didn't like the sound of that, and kicked her out.
A year later, Ulli found out that they suddenly didn't want to help Pokémon anymore.
Their plans are to take over the lands.
They have a Stone that holds some sort of power.
Ulli proceeded to teleport into their base, and run off with the stone (due to her having not much energy for teleporting/floating.).
But when she was running away, something happened....
