Kaga is a hidden location in Warrider. Based on dialogue strings found in the game files, it is supposed to be connected to a questline relating to ghouls.
Overview[]
Kaga is a hidden location, meaning that it will only become visible on the world map when approached. The location's scene is missing, therefore attempting to enter it crashes the game. Using an alternate scene and entering Kaga will reveal that two NPCs are located there by default. These are Overseer Drahu and Arethra Pasarev.
As the location's original scene was never present in Warrider's game files, it is impossible to say what Kaga is supposed to be, but based on dialogue strings, it could have been some kind of asylum where people affected by the Ghoul Curse were meant to be treated.
Trivia[]
From the dialogue strings, the player is supposed to be given a quest to find a healer named Darsu and bring him to Kaga so he could help Overseer Drahu find a cure for the Ghoul Curse.
