Inside Kolaador base
At this very base, Rookie One underwent and finalized his training under the command of Commander Ru Murleen in 0 BBY.

The two pilots were immediately alerted from Anchorhead Base and subsequently departed the planet, heading toward Tatooine.
Three years later, the same bar would be visited again by Rookie One.
