I found a way to get to the next map

I mentioned that all of the areas in the game so far, including the Duergar Camp which you can't normally reach yet, take place on the same big map; the game just warps you around as needed to various parts of the map. (This does not apply to the tutorial ship, which is on its own small map and gives you a loading screen when moving to the main map from the ship.)
There are two more large maps not reachable yet, SCL_Main_A (short for Shadow Cursed Lands) and BG_Main_A (short for Baldur's Gate). They're unreachable because a map transition of some sort is needed to get you there, and nothing that exists on the main map can transition you to the next one, even in the (not-normally-reachable) Duergar Camp of the main map we can access now.
But now I found a way! Use the item spawner to spawn this item ID -- ca8c2b8f-4749-49c1-bd4a-b8d22033cf2c -- and a statue will appear like the pic below. Interacting with it will give you a new option to teleport to, called | High Road - Shadow Cursed Lands |.
Going there, it's just an empty skybox, there's no land anywhere (i.e. no assets that it loads are downloaded to us). The player can't move and even teleporting around through Cheat Engine didn't help me find any land. However, I was able to use Disable Fog Of War and see / scroll around this whole second map. I show part of it here. You can see more parts of both this and the (still impossible to reach) BG_Main_A map by clicking the first link in my post here, though those were just pasted together from minimap files and are not arranged the same.
Hope some of you found/find this entertaining! If more map areas are released, this can give you a head start on reaching them.
Side note: This is more obvious, but you can also spawn Portable Holes with 209445cc-3b30-45d8-8109-9885f3614d0d although they don't do anything currently.
