For Drewbear as a Birthday present. I only saw your challenge tonight so I cranked this thing out as quickly as possible.
This thing completes four challenges at once (though only two intentionally): Bright's 24-hour challenge, Drewbear's non-sight/hearing sensory effect challenge, Bright's 'weapon unrelated to fightan good' challenge, and Djoric's challenge to update a pre-Mass Edit article. This one is based on the (rewritten)version of SCP-267 - Vorpal Sword, the author of which I sadly do not know and so cannot credit.
