This is an Illustrious lora for the style architecture from the Necron faction from Warhammer. The Necrons are a group of ancient space robots that used to be ancient aliens. Long story, so look it up if you're interested.
A weight of 1 to 1.5 works well with this with most models. Sampling Steps of 15 to 35 works well with most models, as does a CFG Scale of 3.5 to 7.5.
