Obtain the Coruu Access Crystal from Overseer Seylanna. Use it at the Coruu Control Console to shut down the manaforge and return to Caledis Brightdawn. Performing quests for the Scryers will cause your Aldor reputation level to decrease.
1x Manaforge Coruu Shut Down
Thalodien told us of your success in disabling Manaforge B'naar. He expects a repeat performance here and asked us to keep an eye out for anyone using a crystal to access the console inside. Overseer Seylanna holds the access crystal, we're sure of it.
Go back in there and finish the operation. No need to be stealthy anymore; get the crystal, begin the shutdown, kill the technicians trying to stop you and get out.
Hurry, it won't be long before Kael's lapdogs sniff us out.
