There is a bedroom in one of the towers of the Castle of the Pony Sisters, superbly preserved under many layers of spells meant to keep it safe and secure, waiting upon the return of its occupant. Decorated in navy, violet and black, it is a safe guess as to whom it used to host in its glory days.
The east-facing windowsill is of no particular immediate significance. Like all the others, it holds objects from a bygone age, relics of past adventurers who found themselves at odds with the Sisters and fell against them. However, upon this particular windowsill rest two nondescript items that differ from all the others in that room. To anypony who were to see them, nothing about them screams that they are from another world. They lay there, safe in their inconspicuousness, silently waiting.
The ship in a bottle and the tricorn hat sit on their windowsill, from which can be seen, with an extremely good eye, the city of Baltimare and Horseshoe Bay, waiting for their master to reclaim them.
Edit - As suggested by the comments I should note that this story will not be up for crossovers with other displaced. Yet.
