Destruction

Alrighty for all you older pokemon fans (Or anyone who's seen pokemon temple of the sea) This includes aspects from different regions though most should be taking place in Galar. You're one of the last remaining Atlantean's after the small hidden island that the few hundred of Atlanteans called home is decimated, with you as the lone survivor and last of your kind you and Lugia must run from the threat that planned to eradicate your race. You meet a certain champion along the way.
Leon is the main focus, however their is hinting of other ships.
