Executor Ingo Astrodius is a high-ranking agent of House Astrodius. Cruel and sadistic, he interrogated Mesper Sorgowin for information regarding First Landing, the Explorers' Guild, and Roanokae Camp. He manages affairs within the city's walls, a master of deception and politics.
He's also a strong psychic, allowing him incredible foresight and divining powers. He uses these powers of augury alongside his sister, Executor Irma Astrodius, to maintain the Overseer's hold on Javervale.
At some point, he deserted his post in the Whistle-Crags and cut contact with Irma, forcing her to rely on the Guild. During Blood Ties, Ingo was discovered at the bottom of the inland sea in the Iron Front. He was transformed into a Weremegalodon, having lost his sense of self. The party stopped his rampage and resuscitated him whereupon he asked the party to wait a little longer to let him finish his task. He promised to return to Javervale as soon as his job was done. After a few minutes, Ingo broke a seal of Monday and teleported to Javervale using a device very similar to the Guild's recallers.
During Underworld: Rebellion, Ingo and Wulf Astrodius were seen on night duty hunting Vampires. The following night, they fought off rebels and Vampires attempting to take over the city. Ingo polymorphed a Vampire into a rat, but was dominated by the same Vampire soon after. Irma's magic helped him break free of the mind control. Following that, he and Wulf raided the rebels' base and rescued their prisoners.
