Hot Spring Villa

One day, Gale will send you a letter with a proposition for you:

Find Gale and speak with him.

If you accepted the mission, wait for Albert to send you a letter with the next steps:

Head to the Research Center and talk to Petra. Give her TBD Data Discs and wait for her letter:

Assemble the Automatic Water Engine and Boiler and bring them to the Western Plateau. Place them at the designated locations near the water. Report to Gale that you've finished the job.

Soon, a letter will come in the mail from Gale:

Attend the ribbon cutting ceremony to gain access to the Hot Springs Inn.
