Multiverse SH-16

Multiverse SH-16 is the largest known Multiverse, being over 2 times larger than a Megaverse. Due to this, Multiverse SH-16 is contained by a "web" of over 8 Megaverses strung together which are collectively larger than Multiverse SH-16. Multiverse SH-16, due to its size and valuable resources, has been invaded and conquered by countless civilizations, and is currently being fought over by 3 (now 2) large empires.

The Iltati
The Iltati are a civilization native to Multiverse SH-16, and they first appeared around 1029 LPT. Over the LPT, The Iltati have grown extremely powerful, and conquered most parts of Multiverse SH-16, even sending spacecraft outside it. The Iltati used to be controlled by a powerful god known as The Eye, although they have since escaped from the low-Multiversal-level entity.

The Outsiders
The Outsiders are a species from outside Multiverse SH-16, first arriving in 1034 LPT + 14 SPT, at the same time The Hwprgtwkantf was disestablished. The Outsiders first settled along the outer areas of Multiverse SH-16, although they started moving inwards in 1035 LPT. The Outsiders and The Iltati have fought each other countless times, most notably in 1035, in which an extremely large war occured between the two.

It is thought that The Outsiders are related to The Hwprgtwkantf in some way or another.

The Annihilators
The Annihilators are a civilization native to a universe contained within Multiverse SH-16. In around 1030 LPT, they developed technology sufficiently advanced to let them escape from their universe. The Annihilators grew much slower than the other major civilizations, and encountered The Outsiders after the war between The Outsiders and The Iltati. The Annihilators would come into contact with The Iltati soon after in 1035 LPT + 1 SPT, starting another war for control over Multiverse SH-16. The Annihilators lost, causing them to lose key universes and devastating their military. In 1037 LPT, The Annihilators were virtually wiped out with the combined forces of The Outsiders and The Iltati.
