Ps3 – Cannot find Aela on second werewolf totem

It is somewhat known that most areas have some sort of scaling mechanic. If you have a quest that is quite difficult it could be a number of things:

• The game's difficulty setting
• The level of the skills you are using affecting how well you can do combat
• the scaling, when combined with the difficulty setting, has made the enemies much too difficult
• The equipment you are currently using
• The combat strategy you have been using has been inefficient and it hasnt been a problem until now

Try setting the difficulty lower and see how low it needs to go before it becomes managable. It may just be that the scaling for that quest is off.

I quote the Elder Scrolls Wikia:

At the end of Raldbthar there is a Dwarven Mechanism which you lack the necessary item to activate. (First Dark Brotherhood Contract Area For Muiri)

The item is an attunement sphere found in other dwemer ruins. To unlock the mechanism you need to travel north of Winterhold. Carefully walk down the mountain, or jump off the bridge path to the college and pray you land in the water (not suggested) then swim north past Skytemple ruins, to a cave called Septimus Signus's Outpost. Once you have talked to Septimus he will give you a quest called Discerning the Transmundane and give you key to open the Dwarven Mechanisms.

Raldbthar connects to Blackreach (by going through the Mechanism) which is part of the Discerning the Transmundane quest, so if you dont want to explore the location Septumus suggests or if you already went through that gigantic location and dont want to retun yet, then you can ignore the mechanism.
