Ullyne, the Personification of the Void, Order, and Technology, is the cyborg Voidan operator of the All-Spectating Temple, a mechnical marvel of the Insectans that was later reused by the Asterians before passing down to her. She can control the walls, entities within, and the looks of the Temple, and the Temple will teleport to various, former Aster Empire Colonies periodically before recharging at Yellowstone. Despite her reputation as a Devourer of Worlds, Ullyne has actually enlightened civilizations and helped them more times than planets she tore apart, but at the same time expects those she helped to get something in return (those who did not and decided to exploit her and their planet to only make themselves stronger, were the ones destroyed). Ullyne is quite friendly, mischievous, and calculated/wise at heart, and beyond the human concepts of "Good" or "Evil" (only does what is necessary for balance).

Her "Red Eyes" on the face are actually heat-sensing glands that are more functional in her true form (skin here is humanoid form), with them colored like hot, flowing magma. She also has an alternate appearance for this form in the UTDR and Terran Tales continuities.
