“I’ve heard of some people trying to map out the Great Crystal during their XII playthroughs so as not to keep getting lost, but such a task would be long and frustrating and definitely not worth the trouble.”
~ Livvyplaysfinalfantasy during her current insightful FFXII playthrough
I love making maps, and I took Livvy’s comment as a challenge. Here’s the fruits of a week’s labor.
I’ve divided my Giruvegan Great Crystal map into two parts, one for the lower levels which you have to traverse for the plot, one for the upper levels that masochists explore for valuable and unique items and prey, including Excalibur, Ultima and Omega (Mark XII). My notes below will help you find all the treasures and understand the naming conventions of the rooms so that they’re not just gibberish.
