alot of people waited a long time for this youtube series...
it's a fan project, so it's not represented by Nintendo, and is basically a guessing game of what happened to Link from Ocarina of Time and Majora's Mask, of the events after those 2 games... it's all speculation what happened to Link during that timeline...
anyways the series just started... and is not Canon, but seems to do a good job anyways...
take a look
