Vermin
A d20 fantasy roleplaying game set at street level in a dark city, where players portray intelligent vermin rather than human-sized adventurers. Rats, mice, sparrows, squirrels, toads, roaches, and lizards use tools and maintain hidden communities while avoiding discovery by humans, the city’s greatest threat. Character creation, experience, combat, feats, and skills follow the rules of the Dungeons & Dragons 3rd Edition Player’s Handbook unless otherwise specified.
战役设定（游戏世界）基于网格（使用方格地形进行移动/战斗）技能型（购买或获得技能）职业制（飞行员、巫师、科学家等）
