Dialogue:
 * "Welcome Traveler! It's so exciting to see a group of new people attempt Ascension. One can only hope that you'll fare better than those who've tried in the past, myself included of course! I just spoke to some of your friends and suggested that they go out into Skyward Reach to take a look at the mesa. You should also have a look, and then come back to give me your impressions. I'm recording the impressions of travelers for posterity."

Walkthrough
Step outside (bring henchmen/your party too!), and just follow the people on the short walk to the top of the mesa. On the way there will be quite a few Hydra, just kill them and move on. The leaders of the party walk quite slow and seem quite aggressive towards any Hydra they see. Also, they can get killed and it won't affect the outcome of your meeting on the top of the mesa.
