Be aware that every member of your group needs to have this mirror quest done in order to be able to progress further inside this instance.
If someone in your group is unsure; have them check their quest journal, or right click the mirror and see what option shows up. If they can select "Enter the Mirror" they can enter to the next floor. If they can select "Gaze into the Mirror" they need to get and/or finish the mirror's quest.
Once you have "entered the mirror" the only way to get back down is to evac or die. Clicking on the mirror you exit from will zone you out to The Shimmering Citadel, possibly locking you out from the instance.
Clear a path between the first room and the room with all the pedestals.
Run to the South-East room and click the mirror to get your next access quest
Do the first Cyclops ring event.
Take all 9 statues off the table in the first room and move them into the pedestal room.
Inspect each statue and it will have a number on it.
Inspect each brass (light brown) pedestal along the edges of the room, not the middle. They have numbers on them too, numbered 1 to 9 in a counter-clockwise order.
Place each statue on a pedestal so the numbers match, either at the top of, or at the base of the pedestal. You did it correctly if the statue does a /cheer emote and you get a message saying "the statue clicks into place".
When the last statue is placed correctly, 9 linked cyclops mobs will spawn on the pedestals in the center of the room.
Kill them all and statues respawn in the first room.
Do the second Cyclops ring event, which is similar to the first ring event.
Move the 5 statues off the table in the first room and place them on their corresponding steel (turquoise) pedestal along the edges of the room, numbered 1 to 5 in a counter-clockwise order.
When the last statue is placed correctly, 8 linked cyclops mobs will spawn on the pedestals in the center of the room. Kill them.
Do the third Cyclops ring event, which is similar to the previous ones.
Move the 4 statues off the table in the first room and place them on their corresponding platinum (light blue) pedestal along the edges of the room, numbered 1 to 4 in a counter-clockwise order.
When the last statue is placed correctly Aysor the Mighty, a 63 ^^^ cyclops, will spawn. Kill him.
Aysor's eye, a 63^^^, or 64^^^ evil eye, will now spawn in the exact location that Aysor the Mighty spawned. Kill it for your quest update.
