Quest Stages - TG08B (Blindsighted)

StageObjective
10 Travel to Irkngthand
I'm on my way to Irkngthand, a vast dwarven ruin that supposedly contains the legendary "Eyes of the Falmer." Karliah and Brynjolf are waiting for me within. Together we hope to stop Mercer Frey from stealing the Eyes and escaping from Skyrim with the Skeleton Key of Nocturnal.
20 Speak to Karliah
I've entered Irkngthand, a vast dwarven ruin that supposedly contains the legendary "Eyes of the Falmer." Karliah and Brynjolf are waiting for me within. Together we hope to stop Mercer Frey from stealing the Eyes and escaping from Skyrim with the Skeleton Key of Nocturnal.
30 Locate Mercer Frey
Karliah and Brynjolf have joined me in my exploration of Irkngthand, a vast dwarven ruin that supposedly contains the legendary "Eyes of the Falmer." Together we hope to stop Mercer Frey from stealing the Eyes and escaping from Skyrim with the Skeleton Key of Nocturnal.
40 Slay Mercer Frey
I've finally located Mecer Frey within the ruins of Irkngthand. He seemed to be expecting us, and I'm afraid he led us here with the express purpose of eliminating the Nightingales once and for all.
45 Retrieve the Skeleton Key
Mercer Frey, betrayer of the Thieves Guild and Gallus's murderer is finally dead. Upon his death, a wave of magic issued from his body and has caused the already crumbling chamber to collapse and fill with water.
50 Escape from Irkngthand
Mercer Frey is dead and I've recovered the Skeleton Key of Nocturnal from his corpse. I need to escape Irkngthand before the place collapses around me.
60 Speak to Karliah
Safe from the dangers below, Karliah, Brynjolf and I finally have a moment to breathe. Mecer Frey is dead, the Skeleton Key of Nocturnal is in my possession and, most importantly, the Nightingales have survived.
200 Karliah, Brynjolf and I have slain Mercer Frey, escaped Irkngthand and recovered the Skeleton Key. All that remains is returning the artifact to the Twilight Sepulcher where it belongs; a journey I must undertake alone.
