There are five datacrons on the Imperial faction version of Taris. The green endurance, blue, purple, and orange mastery datacrons require some finesse with platforming, while the yellow presence datacron is quite easy to get. They provide moderate attribute bonuses. All five are required for the Taris Datacron Master (Imperial) achievement.
