*In [[Warhammer 40,000: Rogue Trader]], the term "Hive-tyrant" applied to the ruler and primogenitor of the whole Hive Fleet - they were described as immensely psychic, huge, bloated with eggs and virtually immobile. The destruction of this Hive-tyrant would disperse the fleet.{{Fn|4}} This description fits the Norn-Queen of more recent publications. It was during the [[Warhammer 40,000 2nd Edition Rulebook|second edition]] of the game that the position of the Tyranid Hive Tyrant in the Tyranid hierarchy changed to its current position; not the highest embodiment of the hive-mind, but the largest version commonly encountered in battle.{{CME}}
