Firstly, I think The Box has been in the city about a year. Long enough for rumours of the odd unborn to spread, for the urban myth to be seen by more and more people, for the myth to become a nuisance, and eventually for enough of the public to complain (20 reputation) to the council. Being burried in a trunk is kinda a negative favour.
So...we are going with rust talk and steam talk being able to get a message across?
Reminds me of a anecdote in Jared Diamond's "Collapse" where Jared, an English speaker, apologises to a man for "push im your wife" poor Jared, the man was very angry.
Anyway, foundation to pidgin can cause terrible misunderstandings. Could be treated like Aloof? or Reviled?
