Master Order embodies the principle of uniformity, orderliness, and immutability. It is one of a small class of cosmic beings who seem to have no personality beyond the abstract concept it represents. (Others in this class of beings include Death, the In-Betweener, and Lord Chaos.) The origins of these abstract entities are unknown. Master Order, along with its "brother" entity Lord Chaos, were first observed during the final war with Thanos, the mad Titanian who worshipped the embodiment of Death. Master Order and Lord Chaos apparently manipulated Spider-Man's critical role in freeing Adam Warlock from his soul-gem to defeat Thanos. The extent of Master Order's power or scope of influence is unknown. Apparently, Order and Chaos try to maintain a balance of power between them for the wellbeing of the universe. (Eventually, according to physics, the energy and matter in the universe will succumb to entropy, or the maximum state of inert uniformity, meaning that Master Order will ultimately dominate.) Master Order and Lord Chaos may simply be aspects of Eternity itself. Their powers, nature, and function remain unknown at present.
