Dragons' Shrine

Oh wow great event bro.
how make that custom events and new maps?! I'm not good in making events but making dungeons is so-so.

I believe the custom events part of this project was done mostly or entirely with FF6Tools:
https://everything8215.github.io/ff6tools/ff6tools.html

It has an event editor as well as a map editor.
Alternatively I'd imagine you could do it the old fashion way and use a hex editor and reference the event command document.
