The twins' group made their own preparations as well, particularly when it came to Rean's airplane. It had always been a prototype, never truly reaching a final version. Rean was constantly improving it whenever he came up with a new idea or discovered a way to make one of its systems more efficient. Even after returning to Besgol, that habit hadn't changed.
This time, however, Rean decided to consolidate everything he had done so far rather than introduce any further upgrades. Making significant changes to the airplane and then leaving Besgol for such a long journey would be a terrible idea, especially if those changes required materials they couldn't obtain along the way. Therefore, his final adjustments focused entirely on reliability, ensuring that every system worked as intended under the conditions they expected to encounter. No new upgrades were introduced.
