Thief

Thief is a classic stealth dark low-fantasy game series where you play as Garrett, a thief, who gets entangled in supernatural goings-ons, including an Evil Nature God amd his Beastman amd Druid army, a Steampunk version ofbthe Adeptus Mechanicus, and fanatics obsessed with warhammers.. It also has a fanmade tabletop setting for the original setting, from before the series was given a shitty reboot set in a Victorian Era instead of Art-Deco Steampunk Medieval. https://thief.fandom.com/wiki/Thief:_the_Role_Playing_Game
