The group 'The Elite Three' refers to Stripes, Shadowlurker, and Dark Link. The three who are closest to Zalgo, and who hold the (shared) second-in-command position for Nezperdia. This is mainly because:

Stripes: Zalgo's first-born, and the princess/heir to the throne.

Shadowlurker: Zalgo's sole proxy.

Dark Link: Zalgo's right-hand-man.
