Forum:When did Vader first learn of Luke's existence (Post-ANH)?

In Vader's Quest, he discovers the name of the pilot who destoyed the Death Star from another captured rebel pilot, and this happened less than a month after the events of AHN. However, I seem to recall somebody here saying he first learned of Luke while meeting him and duelling him. It was in some novel, I think. DarthMRN 22:37, 15 October 2007 (UTC)
