Library is no longer maintained. Crests on Tracker are generated dynamically, and you can use https://www.simbiat.dev/fftracker/crests to do that manually.
Library of merged Free Company and PvP Team crests from Final Fantasy XIV.
FFXIV Lodestone presents crests (logos) for Free Companies and PvP Teams as a set of (up to) 3 images overlayed over each other. https://github.com/Simbiat/simbiat.ru merges them, though for convinience. For the sake of the same convinience resulting images are split into this separate library.
If you want separate components, you can download them from here.
