So you have found my notes, Player.

I was observing the Cleanup Squad Outpost as always when a huge mob of Indratu Legionaries suddenly mobilised.

Until then they had always moved in smaller groups. I found this perplexing.
So I followed them unobtrusively into the Nute Warrens.

Of course, I would have been lost on my own. It would have been dangerous without Barantina.

But I haven't figured out what the Indratu Legion is up to yet.
According to this document, the blue ray of light we saw in front of the Nute Warrens comes from an Aether Transmitter.

We only have a little time left if the Aether Transmitter is already in operation. We have to get to the Indratu Fortress right away!

If you follow this wall, you can infiltrate the Indratu Fortress unnoticed.
We need to make ourselves scarce as soon as possible, because nobody knows how the Indratu Legion will react to the loss of their brigadier.

We also have to report to Perento at New Heiron Gate.
