Maiq is an "easter egg" (though that stretches the term) because he's difficult to find, and he's an inside joke, since he's been in the other games doing the same thing. He makes fourth-wall-breaky references to game mechanics and removed aspects, like mentioning fishy sticks.

If there's a "Giant's Club" weapon in TES:VI that the player can pick up, but it's enchanted with an effect that only allows partners to wield it, that would be an easter egg.
