Per the custom, there's a short fiction piece detailing the lead-in to the event, which continues the trend of Final Fantasy XI's moogles being portrayed as inscrutable meddlers. The holiday proper begins on April 27th, with the usual procedures. Talking to an event moogle gives you a special blade, and finding a moogle in one of several zones lets you enchant the blade to hunt the local armor. You won't be able to fight anything else, but it's all worth it when you slay the creature and get your ever-coveted cosmetic event rewards. In short, it promises to be fun times for adventurers of all levels, although possibly less fun for animated samurai armor.
