Libellus

Libellus is a specialized reference utility designed for Linux environments, created to display tabletop role-playing game information, specifically focusing on Dungeons and Dragons content. The application retrieves and organizes rule sets, monster statistics, spells, and campaign lore into a stylized interface that prioritizes readability during gameplay sessions or preparation periods.

Published under the GNU General Public License version 3 or later, the software allows users to access rules and campaign details locally on their machines. It serves as a digital compendium for game masters and players who want a dedicated reader for rulebooks and reference materials without relying on web browsers or heavy online services.
