Ring World background from Halo.

Trigger: bghaloring

Default:
bghaloring, horizon, sky

Night:

You can prompt/LoRA in a character, but may have to increase the weight of the ring trigger and or LoRA to compensate on some checkpoints. See my samples for examples and ideas.

Works well with other LoRA, see samples!
