Warhammer 40,000: Space Marine · Omarchy Theme

"They shall be my finest warriors, these men who give of themselves to me. Like clay I shall mould them, and in the furnace of war forge them."
— The God-Emperor of Mankind

An authentic, modern grimdark theme for Omarchy Quattro. Centered around Captain Demetrian Titus, the Ultramarines, and the Adeptus Astartes, it pairs deep Void Hull Black canvases with the regal brilliance of Imperial Auric Gold, battle-forged Macragge Blue, Purity Seal Crimson, and Vellum Parchment typography.

Rotating Logo Assets (fastfetch-logos/)

The cogitator dynamically discovers all images in fastfetch-logos/ and cycles through them sequentially on each invocation:

• Automatic Cycle: Cycles automatically every time fastfetch runs in your terminal.
• Manual Pinning: Run ./set-logo.sh to see all available logos and pin any one by index (e.g. ./set-logo.sh 1).
• Dynamic Extensibility: Drop any .png or .jpg into fastfetch-logos/—it will be automatically discovered and scaled with zero distortion.

Wallpapers Included (backgrounds/)

Cycle through the wallpaper gallery at any time with Super + Ctrl + Space or:
