Light Blade

One Christmas there was gift addressed to you that no one could explain or say it was from them. You opened it and it turned out to be a real life lightsaber. But not just any lightsaber, but a Light Blade variant, one of the rarest kinds of lightsabers. It is a lightsaber that has a sheath and is ignited at all times inside the sheath. This makes it very powerful and extremely bad ass. This Light Blade happens to be able to talk but only to you. You can choose what colour the Blade is.
