The Thayan in the Peerage ward sells (With a successful Persuade check) 3 bundles
Bundles of Planar Filth, Fish Scales and Quartz Crystals.
All three cost 1 GP and none of them function, they all bring up an error (Which, sorry, I failed to note down at the time) when trying to unbundle them and the items are destroyed with no new items generated.
You can find the error message here: https://www.efupw.com/forums/index.php?topic=699672.msg727349#msg727349
