Lakcis:
Excellent! Thank you!
I want you to speak to Chesha in Exploration Zone 1, and tell her that "Lakcis is ready to go to ruins whenver". I realize they won't allow me in just yet, but I want them to know that I'm snapping at their heels. It's imperative that I gain access to the ruins!
Now, to get inside, I believe you can use the Ye Sagira Teleportation Device. Go, and be safe!
