Uh... alien? I'm not sure it really has a name, exactly. But here...

[He'll draw it and try to hold it in a way that it will show on the video. It's long (not two meters though holy hell) and curved, a faint purple glow running up along the blade itself.]

Normally I can transform it from this to a knife and back, but since I got here, it's been stuck in this form.
