That sound about right. More likely a 'fantasy parallel universe' where sword and magic is the term notion and fantastic different races exist other than the humans.

Since this world Ainz and his NPC transported had no official name as it is called the 'New World' it maybe basically a world that branched off from YGGDRASIL but a very lower world unlike the Nine Worlds where magic and creatures is on a whole higher levels and materials are godly existence. Even though this LN, this anime is fiction I might referring this into the 'Bubble Multiverse Theory'. Where countless universes floated, distancing itself from each other existence and continuously forming new bubbles of reality. The game itself might delivered from that and where the 'New World' either a branch, a seed, or a leaf flown off away from its birthplace and drifted among the countless bubbles but have still connection into the 'World Tree' by an unknown force (possibly Dark Matter related) in which is why so many players from the game ended up in that world where reality became real as the game worlds itself are just man-made but still no idea how they get there in the first place. In other isekai, it always explain how they came up to another place by either "summoning magic" or "Gods intervention" but others remain unknown like here in Overlord.

The author might have an idea or not.
