Most mobile interfaces settle for flat pastels or glassy neon gradients. If you want something genuinely atmospheric with heavy fantasy grit, Dragonfall Keep steps in a completely different direction. Crafted by Old Marlo Games, this custom package reinvents your Xiaomi, Redmi, or POCO device into a fortress under siege. From blazing lock screen sequences to heavily textured hardware icons, it treats the screen like an unfolding battleground rather than a generic app grid.
Here is an in-depth breakdown of how the interface feels in daily use, who it suits best, and how to get it working cleanly on your setup.
Forged Iron Shields and Blazing Embers
The centerpiece of Dragonfall Keep is its bespoke icon set. Instead of typical rounded squares, Old Marlo Games crafted 127 individual icons resembling forged iron battle shields. Each shield features a dark, pitted metallic border that frames deep charcoal centers, lit from within by ember-hot glyphs.
System apps—like Phone, Messages, Settings, and Gallery—get distinct fantasy interpretations without sacrificing readability. The phone dialer icon trades ordinary handset curves for a hot-stamped rune, while the camera looks like an iron-encased scrying glass. The high-contrast color scheme pairs soot black and steel gray with searing orange highlights, making app shortcuts immediately recognizable against both pitch-black wallpapers and detailed scenic artwork.
Because these assets are built as scalable vectors, edges remain pin-sharp regardless of your display density or grid size. Whether you run a dense 5x6 layout or a spacious 4x5 setup, the borders never blur or bleed into neighboring widgets. For apps outside the 127 custom-crafted titles, the theme applies a matching iron silhouette mask, preventing mismatched shapes from cluttering your home screen.

Siege Engine Lock Screen and Fluid Ash Transitions
While the icons carry the home screen, the lock screen delivers the real theater. Waking the phone triggers a dynamic siege scene: a burning stone fortress at dawn, framed by drifting ash, waving banners, and a towering dragon perched atop the keep. Every time the panel lights up, the dragon lets loose a stream of fire that rolls across the skyline before settling into a warm ambient glow.
The tactile feedback during unlock is where the craftsmanship shines. Swiping upward triggers a custom transition where the entire stone landscape dissolves into drifting embers and dissipating smoke, revealing your home screen underneath. Plug the device into a fast charger, and the stone ramparts brighten with molten light as the battery percentage climbs within a blazing rune circle.
The aesthetic extends directly into the Control Center and Status Bar. Toggle tiles mimic dark cast iron plates that flare into molten orange when toggled on. Battery meters, Wi-Fi indicators, and signal bars abandon stock flat accents in favor of carved runic notches that match the overarching medieval siege tone.
Mixing Components and Modular UI Flexibility
You do not have to commit to every element to appreciate Dragonfall Keep. Thanks to the modular architecture of HyperOS and MIUI, you can easily separate the icon pack from the intense lock screen mechanics.
If you prefer clean productivity setups, pair the 127 iron shield icons with a simple pitch-black wallpaper or a clean architectural photograph. The glowing orange accents provide just enough color pop to keep the interface legible under bright sunlight while preserving an understated, stealthy look. Conversely, fantasy enthusiasts can keep the animated dragon lock screen active while retaining cleaner, minimalist icons on the app drawer.
Gamers, tabletop roleplay fans, and dark-mode purists will feel right at home here. The heavy contrast reduces eye strain in low-light environments, and the absence of glaring white UI panels makes night navigation easy on the eyes.
Setup Walkthrough and Bypass Tips
Installing third-party .mtz themes requires slightly different steps depending on your specific ROM region and system build. Because global HyperOS builds frequently restrict direct imports via the default Theme store, having a backup plan makes the installation seamless.
1. Standard Import Method: Open your native Themes app, head to your profile screen, select Themes, tap Import, and locate your downloaded file. If supported on your region, simply tap Apply.
2. Theme Editor Bypass: If your device returns a third-party authorization prompt (such as Error 402), load the file through a community utility like MTZ Theme Tester or Theme Editor. This parses the layout and caches it directly into your local offline storage.
3. System Restore Route: For deeply locked firmware, convert the theme via an MTZ-to-BAK tool, drop the file into your device backup folder, and restore it locally through Settings > Additional Settings > Back Up & Restore.
To prevent the system from resetting icons after memory optimization cycles, keep your theme assistant pinned in the background, or re-apply the pack directly under Customize Theme > Icons.
