did noone read the actual text that went along with that cutscene?
seriously...
the dark links are the mages who used an evil power to defy the goddesses
link was killed by one so that the mage could take his form
then the goddesses kill the mages.
it was the story of the tribe that was banished to the Twilight and became the Twili.
