Well, the strike team was lead by a jedi named bastilla, who defeated revan, and in revans last few moments she felt sadness for him, so she took his unconscious body to the jedi counsil, where they wiped his memory so they could reteach him in the ways of the jedi. Revan (not knowing he was revan) started to follow in the footsteps of his former self, trying to figure out why he became evil. Eventually he learned that malak was going to use the star forge and he stopped malak, in the process learning who he really was. Then the story goes on to him marrying bastila and lah blah blah
