EURAPAC Meta-universe/APAC Universe, commonly known as APAC or First Tetra-quadrant, is both the name of 1st known universal tetraquadrant and a collective term referred to space objects, galaxies and polities across known space with same elements: they are either direct, indirect descendants or influenced by Asian-Pacific cultural spheres from ancient Earth; hence the name APAC. The majority of them are of East Asian, but others such as Arab, Persian or ASEAN cultures also stay strong. Outside images are those of EUROPA - their counterparts from Europe.
By the time of the current era, the APAC is known as technological pillars of civilization. The main area of this tetraquadrant fans out from Milky Way galaxy North-Northeast-Southeastward, but their associates locate all over the universe. APAC Universe faces the unknown space on Eastward, AMERICA on Southward and EUROPA on Westward. The JIOR, the Oceania and its associated nations are APAC's farthest points to the East, facing the unknown on most of their borders.
The APAC Universe occuppy one of two largest universal corners in known space, equaled only by EUROPA. Like the later, the only one thing that make their civilizations similar is that APAC space is largely influenced, directly or indirectly, by Asian Pacific cultural spheres, notably are East, South and Southeast Asia, as well as Arabic-Persian and Pacific Islands ones. APAC sovereign space faces EUROPA on the West, NON-ALIGNED on the South and unknown space on the East. Similar to Asia on ancient Earth, APAC is also divided into North, East, Southeast, South, West and Central regions, in term of astrometry.
APAC is the technological pillar of entire known space, home for some of the most advanced, scifi-liked worlds and megalopolises. A typical city in APAC space (pic on the right) usually contains several dozen to several hundred millions sentients, humanoid or not, and possessed powerful technologies, enough for self-sufficient for centuries. Some notable ones such as Saigon-Gia Dinh, the Confederates' capital, Rekilawa in Ceylon space, or the Neo-Seoul, capital of NKR. APAC is also where several individuals whose exploits, adventures or actions had since contributed into shaping and consolidating pan-multiverse community, such as Director-General Amakawa Yuuto of the Confederates, Emperor Hyoudou Issei of the MEN or Great Lord Naoe Yamato of the MWH. Before long, if EUROPA is where you would find the recreation of various fantasy-themed worlds and systems, with knights, magic, witches... just like in fantasy-based works, APAC is the place whereas ecumenopolises, massive cosmological constructions, Dyson spheres... are the norms, like scifi works.
Northern APAC, or Northward APAC, is the sovereign space that stretch along much of APAC Universe. Over time immemorial, North APAC was inhabited by civilizations with one way or another connection to North, East and Central Asian cultures; many of them were revived indigenous ancient ones. Unlike their neighbor Eastern, the power's balance in the North has rather been stabilized and hegemonized. For millennia, the Siberian Combine, the Mongol World Hegemony, the Nenetsia Pact, the United States of Yakutia and the New Golden Horde had maintained their significant influences throughout the region, while facing off much bigger and more advanced great empires from the East and Central, notably like the Manchu or the Turan.
