Kashchey is a major background figure in Arknights, especially tied to the lore of Ursus and the political turmoil around Patriot, Talulah, and the Reunion movement. He is a manipulative, influential nobleman whose actions and ideology help shape several key conflicts in the story. Kashchey is portrayed as a shadowy power broker rather than a frontline combatant, with his presence felt through the consequences of his schemes, ambitions, and the people affected by his legacy.
