'Rusty Maze' and 'Rusty Vault'?

[LibertyPrime]

Does anyone know from which mod these locations are? I came up to them by complete accident. 'Rusty Maze' seems to be a few pipes connected to eachother, and at the end of the 'maze' there are two possible exits: a pipe that leads downards that seems to be a dead end, and the entrance fo this 'Rusty Vault', which seems to be a normal-looking Vault, except it seems to be empty (as in, no enemies), with the exception of this one room that's locked, and inside is a corpse lying on a bed with three 'Vicious dogs'.

If you open the console and click on one asset of the place, you'll see its ID. It will be something like 0A364F21 (I'm improvising). 0A will be the index, the position of the mod in your load order - you can open your mod manager and see which mod has position 0A

Thanks. It turns out it belongs to the mod 'Kidnapped by Fiends'.
