Blank teleport crystal

A Blank teleport crystal is given by Arianwyn at the beginning of the quest Within the Light. The default left click option is to "Chant-to" the crystal, which can only happen when standing at a certain point outside the Temple of Light. If a crystal is clicked when not standing in that location a message appears in the chatbox that says "The crystal doesn't seem to respond at all here." The Blank teleport crystal looks the same as a normal Teleport crystal.
