Return to Shandris Feathermoon in the Feathermoon Stronghold and report your findings.
With the discovery of the strange gazebo in the heart of the Ruins of Solarsal, the time has come to return to Feathermoon Stronghold and report to General Shandris Feathermoon what has been discovered here.
Welcome back, <name>. Your report on this gazebo is most... disturbing. It would seem that even if the naga there were not planning on an attack, their continued presence bodes ill for our push into Feralas. At any rate, here is compensation for your investigation.
It would seem that Feathermoon Stronghold is in dire need of additional assistance concerning the Hatecrest naga. I'd like to offer you the task, if you are so inclined. There is much to do.
