Do you know of or own Space Hulk? It's an old 40K tabletop game with lots of puzzle pieces to create your own campaign levels. This Lora can help create new tiles for you, or even help with campaign ideas. It's not completely perfect, but you can mix and match checkpoints and other Lora to create the style of tiles you want.

The Lora is trained in 2 ways. Tiles and Campaigns.
To generate tiles, use any checkpoint or mix a Lora with the trigger: 'sphulktile'.
and then prompt something like: 'tile hallway', or 'tile intersection'. (Room, corner, etc)
To generate campaign ideas use the trigger: 'spcampaign', and then use a prompt like:
sphulktiles connected as a boardgame with rooms hallways junctions and intersections
Add things like, fire, gore, water by just typing it in after.

I tried training it to number of squares but it doesn't work too well that way. So if you want a hallway or a room it's best to make the height and width of your canvas in the shape of those tiles. (e.g. a hallway could be 1024x300, or flipped, a room or junction could be 720x512 or flipped, a large room could be 1024x680, etc.

It's not perfect, and the campaign ideas are fairly low res and meant as a reference for an idea to build it with the tiles, but stick to the width and height trick it can
make some crazy Space Hulk tiles!

Hope you like it.
