[Tuor of Gondolin]

There could be a loophole for Melian. What's to prevent her from
(metaphorically) wrapping the girdle in plastic wrap and setting
up elsewhere (The willow meads of Nan-Tathren, unspoiled
Lorien, etc.).

EDIT: Note to Anguirel. Mim could come out of this fine. He might
make a bundle with his stand-up act, convert money into jewels,etc.,
leave Doriath just in time and set up in Belgrod or Nevrast, where
he could restart the Petty Dwarf line with some dwarf maidens
attracted by his wealth, or alternately get Melian on the
rebound and have her girdle protect them in Nevrast or
Belgrod.
