Voidsea

'One of the earliest records we have of the Voidsea refer to it as 'Outer Space'. As far as names go, it's appropriate, I suppose - They thought of Space as being 'outside' their worlds, but the truth is the opposite - We are always within it. Our Realms are but islands within the Voidsea.' - Captain Abyss-Breach, 17th Century of the Valhallan Age

The Voidsea, also known as Outer Space, and many other names, is one of the two overlapping realties which exist in the Valhallan Age. It's defining feature is the vast, uninhabitable distance between celestial bodies, requiring the use of advanced technology, biological engineering, or other such adaptations for many lifeforms to travel between worlds while in this reality. In contrast to it's counterpart, the Realmlands, this expanse is often compared to an endless ocean of nothing, hence the name, Voidsea.

As a matter of understanding, the Voidsea refers to the entire reality itself - This would include outer space in it's entirety, but also any realms, stars, other objects within it. To many however, there is a distinction to be made between the Voidsea, and the realms within it - Many would consider worlds like Earth to be part of the Realmlands, but this is purely a matter of semantics and definition. As Earth's geography is not matched, not reflected within the Relamlands, it is considered to be part of the Voidsea.

The Voidsea is distinct from the Realmlands in a number of other ways - Technology that does not work in the Realmlands works within the Voidsea, for example. While a starship might work in the Voidsea, that exact same starship would not work in the Realmlands. Howeer, unlike the Realmlands, the distances needed to travel from world to world is massive, by factors of thousands, tens of thousands, or even millions, depending on the two realms in question.

The discovery of the Realmlands originally lead many across the galaxy to believe that the Voidsea was to become an almost irreverent frontier in terms of travel, conflict, and colonization. This was the exact opposite of what would end up becoming the case - Rather, the Voidsea became one of the two fronts within the Eternal War of Ideology, requiring just as much focus on on a strategic and military level. Battles are fought for any world within reach, and some Factions go to great lengths to hide their Prescence on some worlds, in order to hide technological developments, Taekni training centres, deployments, or launch-points for additional attacks.
