The Morrowroots is the founders' forest hull of Isla Buena in my novel Solarum: The Continuance Crisis: a spinning drum moored near Saturn, lined with old-growth forest, rivers and meadows. Stand on the forest floor and the land doesn't stop at a horizon. It climbs up in front of you and hangs over your head, rivers and all, in cool misty light.

What it does: puts you at eye level among mossy logs, ferns, stream banks and meadows, with the forest rising behind you and filling the sky. The look is illustrated: soft painterly greens, not a photograph.

How to use it

- Weight 0.9 (0.8 to 1.0).

- Always add: the forest, rivers and meadows curve up into the sky and hang overhead

- Start from: wymzra, mossy logs and ferns on the forest floor, the forest, rivers and meadows curve up into the sky and hang overhead

- Good foregrounds: mossy logs and ferns, stream banks with stones, meadows, a small cabin with a lit window, a waterfall into a pool.

- Negative: top-down, map, sea, beach, vehicle, train, text, letters

What it can't do (yet)

- The trigger alone is unreliable: sometimes forest, sometimes a vehicle with lettering. Always give it a subject.

- Waterfalls show about half the time; forest paths don't show.

- The look is illustrated and strong; it pulls photographic prompts toward painterly greens.

- No end-cap cliffs yet (the cliffs and big waterfalls are planned for later).

How it was made

A 3D forest hull built in Python (no 3D software), rendered from 30 eye-level camera spots looking across the drum. SDXL painted over each view with a little help from my Solarum Sea Hull LoRA (that's where the climb came from), repainted only the near band at eye level, then blended the whole picture. 33 pictures, captioned only with what's in the foreground, so the LoRA carries the climbing land. No other people's art, nothing from Flux / Google / OpenAI.

Training: Juggernaut XL v9 base, kohya sd-scripts, LoRA dim 32 / alpha 16, UNet only, 1024 px buckets, AdamW8bit, cosine, LR 1e-4, 15 repeats, released epoch 4 (496 steps).

Made with Claude (Anthropic): Claude Opus 5.5 in Cowork wrote the 3D renderer and planned the method; Claude Code with Claude Sonnet 5.5 on my desktop ran the renders and training.
