Revan mentioned something about Tython during TOR. Maybe this can be it; it has lush forests, a landing bay, and a temple. This should take place after the revelation imo - tasks on Tython may help Revan find the peace (LS) or the strength (DS) needed to face dark-side Bastila and Malak. The peace/strength could be found through trials in the forests and/or meditations in the temple - I want dem stat boosts
. Plus there really wasn't much reaction to the destruction of Dantooine's enclave except for about 2 lines of dialogue. Traveling to Tython can emphasize Dantooine's importance (maybe Jolee or Juhani could propose going there).
Or we could bounce off SH's idea of expanding party member stories; Zaalbar would be a nice candidate.
