Full Immersion [for what it's worth]

> A set of two rapiers bolted together with a single hilt.

The six part sword from Final Fantasy VII Advent Children.

Neyla pauses to think before answering, and then brings up the screen and, in it, the skill tree. There are a few more skill points available, enough to gain one of the two actually buyable skills, but for the moment she re-rolls the third skill (the electric-leaves symbol). The die settles on 3 and the skill's picture is replaced with that of a spear.

She dismisses the screen with a shrug and then responds, "The last one, I think. And something that can be broken into two swords sometimes, if possible."
"How do you mean?"
"Say..a two-edged blade, which is also two separate one-edged blades held together by some slots and pegs, maybe magnets to help. Can magic make something magnetic?"
"Probably, couldn't hurt to ask." He resumes writing, and after a little more walking they enter what looks like an ordinary blacksmith's shop.

"Hello there, I'd like to order a sword made," says the priest, placing the piece of paper on a nearby counter. The man working the forge looks over. "All this, and whatever other enchantments she wants. Money's no problem."
A woman comes out from behind the forge to the counter and picks up the paper, looking at it for a few seconds, then looking up and regarding the two of them. "Int'resting gift," she says, "what else you want, eh?"
