This location is only accessible during certain plot points
The Desert is a small one-time area you'll arrive in after escaping D-District Prison. Aside from the Aero Draw point, there's not much of interest here. Squall will have to split the party, with Selphie leading the second group. The party will remain split for a while, so choose wisely.
Squall's group will hijack a train, while Selphie's will have to drive to the Missile Base.
