The stone forest formations that Elua remembered being in a certain part of the Astral Exclave had survived the realm's expansion and the many millenia, though by the essence currents underground it sat much closer to the center than before - which was just as well for her purposes.
Weathered spires of calcareous rock jutted from the land all over, marked with veins of green and blue. Natural malachite and azurite formations that contained her much beloved copper… which was not the only reason she chose the spot. A truly massive basalt arch stood at one end of the stone forest.
Long ago, the structure had been Acid polished and carved with sigils that were now so old that most couldn't decipher their meaning. She had been a little bored after stealing the realmshard from that Guild, but not quite ready to link it to a personal voidspace. So she'd left this grand marker here as an experiment.
