All we know is she made a break for it. The vessel could easily show up again in Pierrot, or even in the Tailor era before ending up in Nyoze's hands.

Neither is there anything corraborating the idea that Magician kept the sword and it never ended up back in Pere Noel's possession at any point (though I doubt it would, honestly).

There was never an explanation given for how Gast's dad allegedly ended up with the sword when AB-CIR had it 100+ years prior. I don't think we can say for sure what explanation we are given until we pass through the tales telling the time in-between.
