WARNING: spoilers of OOT and HW <3

Sheik: is hiding a face under that mask, doesn't bother taking too much. A bit of a shy person who will kick you in the face if you insult her.

Impa: the Princess' nursemaid. Has been with, Zelda since she was a small child. She will do anything to keep the princess safe.

Link: was a Hyrulian knight in training. He longs to know what face lies beyond Sheik's mask. He also acts odd around clay pots...

Lana: a sorceress who knows her craft well. Becomes good friends with Sheik, and also develops a wonder of what is behind her mask.

Zelda: the princess everyone has been looking for. Zelda will do anything for her kingdom. Even if it means dying, she'll do it. As long as it helps Hyrule.
