Ulquiorra is the Cuarta Espada in Aizen's Arrancar force, which literally means 'Fourth Espada'. This means that he is the fourth strongest. The remains of his hollow mask appear as a broken horned helmet on his head. This has lead to speculations that he is a Vasto Lorde. He has a number 4 tattooed on his chest signifying his rank.
Coordinates are for parking at the start of the trail. This multicache brings you on a journey along Corridor 71 and the Mid State Trail. The cache container is locked away and hidden well. A 3 digit combination is required to open and release the cache. So you must first visit 4 locations. Each location is near an old structure that was part of the old boy scout camp. At these structures are Key Tags that each contain 1 of 4 numbers for discovering the combination. Each Key Tag also contains a 1/4 of a sentence that gives you info about the numbers and the cache location. They are located near the structure but not in or on it. Please be careful with each one. Use your geosenses for many hints will become apparent as your quest continues. Make sure to use online maps (Openstreetmap has these trails on it) and stay on Corridor 71 and The Mid State Trail. Each stage is not far off the trail.
Congrats to LaFountain's for his FTF!
