Y hallo, this is the Demyx that hung out with the DGM group that had epic-huge hammer Lavi.
She didn't take the thing apart to get it up to her hotel room, it was in Checked Baggage all weekend when she didn't wanna carry it around. So yes, the storage room behind the elevators. The thing DID NOT come apart, and they DIDN'T sleep in it.
She brought it to the con in the back of her dad's van, and if you were there Friday you might have seen the interesting time they had getting it out of the back. Yeah, that thing barely fit back there.
As for it being light? XD XD XD don't make me laugh. It wasn't epic heavy, but it wasn't epic light either. It weighed about as much as... How did she describe it? Like a 7-year-old child. She's got a bruise on her shoulder from carrying it around.
I'm gonna make one myself, but probably out of fiberglass insulation foam (and on a slightly smaller scale) for my 3rd uniform Lavi.
