Forum:KB:Luke Skywalker's "death"

I understand that people want Luke Skywalker to eventually meet a heroic demise, but I question this. Why are people presuming Luke Skywalker's death to be between 45 ABY and 137 ABY when it is the job of an author approved by George Lucas himself? --Obi-Wan Kenobody 20:18, April 23, 2014 (UTC)
