You have already found the plans in Nchuleft.

Good. If you were successful, Archmagister Gothren wanted you to have this.

I do not appreciate any %PCRank who tries to trick me. Bring me the plans or else.

Archmagister Gothren was right to question your loyalty and rapid advance in House Telvanni.

Have you found the plans Archmagister Gothren was looking for?

This Dwemer ruin lies west of the town of Vos. Apparently these ruins are what Archmagister Gothren wanted Ainat Sanababi to look for. Archmagister Gothren wants some plans or blueprints from from Nchuleft. Find these plans and return them to me.
