To quote Tataru:

"Anyway, after Yugiri found me, we traveled to Vesper Bay and met up with Urianger. When we told him what happened, he used his magicks to weave a glamour around the Waking Sands."

So, yeah, I don't think that's quite right...Urianger didn't cast the glamour until after the fact.
