you cant get a party unless people join your team, these people are : Carth, Canderous,
Mission, Zaalbar, Juhani, Jolee, and two droids one that looks like R2-D2, and one you can
buy for 4000 credits if you persuade the seller in Tatooine. If you move around click the
map in the top-left corner and click party selection, but in some areas you cant change
your members with party selection so you have to work with the people you have until you
can change members.

if you're still in Taris your team will be in the apartment.
if you steal the Ebon Hawk from Davik after you kill him your party will be in the Ebon
Hawk
