The Hârn Weather Generator plugin allows users to generate realistic weather conditions for the HârnMaster roleplaying system. Based on climate zones and latitude settings from the Keléstia rulebook, users can simulate daily, weekly, monthly, or yearly weather patterns with a single command or button click. The generated weather data can be copied to the clipboard or directly inserted into an active note, making it easy to integrate with game sessions. This tool helps Game Masters maintain atmospheric consistency in their campaigns, providing structured weather details that enhance immersion and storytelling.
