The Quest of the Strength Spell, Clue #10

The Dimentional Mirror

In all my years of study I have learned amazing secrets about psytech. I specially remember when Eria, my assistant brought the strange piece of glass and silver she found in the Fog Lands. For several years we made tests on it, and after a curious accident we finally activated its power. We found it was able to create a powerful teleport field, faster than the best Mythic spell. Unfortunately we never could set a precise destination it would always send the user to a random location in the world. One day Eria accidentally fell into the teleport field, and she disappeared. I waited for her during days, hoping that she would be able to return in the same way. Finally I went looking for her in an epic quest, but I could not find her.
I met a Traveler in the Fog; he told me he saw Eria appear with the mirror in her hands, she looked dazed and confused. She dropped the mirror and walked into the fog.
Nobody saw Eria again, not even the Fog Traveler.
I told him to keep the dimentional mirror; it had no longer a use for me.
