While his summons were busy taking over the Garuda facility, Ashton was busy making plans to storm Tartarus. Unlike the rest of the facilities, information about Tartarus was tough to come by, even information dealers not wanting anything to do with it.
That's why finding Alina and persuading her over to his side was the primary objective. At the moment, Anna was hot on Alina's tail. However, Ashton had requested her not to get into an altercation with her.
