Magic Item Monday: Rug of Concealment

This rectangular, rose-red flatweave rug is so worn, sun bleached and threadbare that it barely manages to cover the 5' × 8' patch of floor beneath. However, anything placed under it seemingly disappears so long as the rug can cover it wholly. Even if a treasure chest sits on the floor below it, the rug will appear to lay flat on the ground. It could cover a corpse, but a person would have to lay down in order to be magically concealed. The rug won't muffle sound or hide light, nor will it offer protection from damage; a teacup beneath the rug will shatter under foot. If it is disturbed, including by anything beneath it, whatever it covers will reappear.

One Rando's Thoughts on Using Lycanthropes

Beoric, with whom I have never shared discourse and don't know from Biblical Adam, made a comment I appreciated on one of Bryce Lynch's reviews: 

There are 3 reasons to use a lycanthrope in a module:

(1) they are hidden, and the challenge is to figure out who is a lycanthrope;

(2) the risk of the curse of lycanthropy, which drives play if somebody might have been infected;

(3) you want a regenerating combat opponent and the party is too low level for trolls.

“Wererats in the sewers” defaults to (3), and is overdone and not that interesting to begin with. The curse has been sufficiently nerfed in 5e that it is really not much more than an inconvenience, so (2) is no longer a serious option.

That leaves (1) as the only remaining option that has any potential to be interesting at all. Which clearly should not take place in a sewer, since you need sufficient non-lycanthrope humanoids around for the lycanthropes to blend in. You could have an encounter with wererats in a sewer, disguised as public works workers or some such, but if *everyone* is a wererat in disguise then no wererats are really in disguise.

It will necessarily have a strong social element. The Thing is a better example of this than most werewolf fiction.
