Gates, at their core, were portals - fractures in reality that connected Earth to other worlds filled with dangers, monsters, and beasts.
That much was clear.
But beyond that, almost everything about them remained uncertain.
From the very beginning, humanity discovered one absolute rule: only those with Titles could pass through. Untitled individuals were completely rejected, unable to enter, regardless of the methods attempted. It was as if the gates themselves enforced a law beyond human understanding.
Inside, each gate functioned like a hostile, self-contained world governed by supernatural forces. If not cleared, they grew unstable over time, the boundary between worlds weakening until it eventually collapsed, a phenomenon known as a Gate Break.
When that happened, the portal would widen uncontrollably, allowing the creatures within to spill into Earth and run amok, causing destruction on a massive scale.
