re: Obi Wan Anthology in the works - Confirmed

Just because they don't know Luke exists doesn't mean the threat of them discovering him isn't real. Obiwan didn't spend 20 years secretly watching over Luke for his own health.

When we're talking about mystical forces like the dark side any number of threats can be attracted to a power, if unknown, source of the light side.

Hell, it doesn't even need to be either, since Tattooine is one of the most dangerous planets in the SW universe.

Any half-way decent writer should be able to tell an adventure story Obiwan might have had in those 20 years.
