Elluwen has task the silver crest, meaning off course sir Croakington to retrieve a garnet studded boot of unknown properties that ended up in cave filled will giant beetle for reason that I'm sure aren't fully explained.
I then find someone else wants the boot and gives even less reason, as they aren't even the one that wants it and they don't say who does.
At the end I can only hope I haven't helped the forces of evil because I have no way of knowing if I did.
