Ah, the Great Library’s crystal, huh? Those things are stubborn enough to need a good old wrench and a bit of elbow grease. First thing’s first—grab a sturdy ladder, a decent pry bar, and a flashlight that can cut through the dust. I’ll give you a quick rundown: start by gently loosening the moss and grime around the shard’s edges. Once you’ve got a clear line, you can slide a flathead in, pry the shard free, and carefully pull it out. Remember, it’s heavy, so brace yourself and don’t yank. After that, you’ll want to wrap it in a soft cloth to keep it from cracking. Got a spare toolbelt? Bring it along, and we’ll get that crystal back in the spotlight.
