What He Did

Organized the logistics of the goblin raid on Sandpoint.

confirmed — T3: “wurde von Tsuto (ihr Bruder) verraten und beim letzten Goblin überfall auf Sandpoint hierher verschleppt”

Why He Turned

He was manipulated and seduced by Lyrie Akenja, who used this relationship to bind him to Nualia’s operation. Whether his commitment to Lamashtu is genuine or purely driven by Lyrie’s influence is not resolved.

confirmed — T3: “Tsuto gehört zu Lamaschtu und kann getötet werden, er wurde von Lyrie Akenja verführt” — “Tsuto belongs to Lamashtu and can be killed; he was led astray by Lyrie Akenja”

Notes

“Can be killed” is an explicit T3 session note — Ameiko told the party this directly.
His defeat is not recorded in extracted T3 sources.
