Assemble Dee-Dee Transport

1. Fairly early in the game, the town will express interest in a system of Dee-Dee Transport vehicles to make traversing the town faster and easier for everyone. This unlocks a series of missions in which the player character helps make a system of Dee-Dee vehicles possible.

2. Soon Petra at the Research Center will send you a letter:
 * I've heard from Presley that you've taken on a commission making a Dee-Dee transport. For this vehicle, you'll need parts made of relics, I'm not sure if you know how to proceed exactly. Come see me in the Research Center and I'll explain more of the details to you.

4. Visit Petra at the Research Center to have the following conversation:

5. Gather the required materials for building a Dee-Dee Transport, including a Small Engine, and assemble the vehicle.

6. Deliver it to Antoine for a reward of experience, gols, and reputation.

7. Go speak to Gale to begin the next mission.

8. Note: This mission can be repeated a limited number of times by visiting the Commissions Board in the days shortly after the mission was initially given.
