Dark Interlopers

The Dark Interlopers were a tribe of sorcerers who, in ancient times, attempted to gain hold over the Sacred Realm and steal the Triforce using the Fused Shadows. In response, the goddesses sealed them away into the Twilight Realm, and split the Fused Shadows into 4 separate shards. They would eventually start the Twili race of beings. They were mentioned to Link by the Light Spirit Lanayru when speaking of the dangers of the fused shadows.

In the narrative given by Lanayru, Dark Links appear to represent the interlopers. After they kill Link (possibly representing normal beings in Hyrule), a clear eyed Link becomes the leader of the group, before the light spirits intervene.
