"As prisoners?" Ashton quizzed Lucia, the governor, "That's the only way to enter Tartarus?"
Lucia nodded, "I only have the authority to collect and send prisoners for experiments. One would require a recommendation letter from the president to join Tartarus even as a gatekeeper."
Ashton was hoping Lucia would at least be able to send him in as a guard. That way, he could move freely and gather information about his father. But being a prisoner would limit his ability to do so.
While he could change his appearance to imitate one of the guards to take what he wanted, it was unlikely that prisoners would be allowed to use their abilities freely.
Considering the undead are in contact with outworlders, Tartarus must have the technology to negate the inmate's abilities. Talking to Viper only confirmed his doubts.
'I won't be able to use [Corpse Parade] to control the undead either.'
