Is that its mass shadow that you're referring to, jaoblias? I guess the answer is a resounding "maybe," though can you remind me where that bit comes from? I can't seem to find any official mention of it. Huh, sorry about that must of been fanon I picked up at some point. Esentially someone somewhere explained that the moon of Endor could have had a greater mass shadow that would pull ships passing the planet from hyperspace causing the oddly high amount of ships crashing on the planet bringing new species. I guess if this were canon it could be explained by the Endor wormhole.
