Discover a World Without Barriers at the Citadel and Operation Safe Place — where getting involved is as simple as playing to earn. You don’t need an expensive setup or a big wallet to join the revolution. Whether you’re on a basic smartphone or an old laptop, you can dive straight into Athera, the vibrant digital heart of our metaverse. As Uncle Funk says, “Zero barrier, infinite potential. You don’t buy your way in — you grow into it.”

Our living economy runs on two powerful tokens that work together seamlessly:

• Courage – the everyday fuel you earn just by playing, creating, completing quests, or helping others. Spend it on upgrades, rentals, and fees to keep moving forward.

• Citadel Token ($CTL) – the solid anchor for real ownership. Use it to claim property, prestige, and permanent assets that last beyond the hype.

This dual-token system lets anyone start earning from day one, without speculation or paywalls. Courage powers your progress; $CTL builds your legacy. Jump in, play, earn, and grow — that’s how you become part of the Citadel and Operation Safe Place today. 

The Citadel Marketplace is the place to purchase all your in-game playable and tradable NFTs. Each NFT serves a purpose and hosts its own unique strengths.

Dual-Mode Combat: Experience the evolving gameplay as we work to seamlessly blend strategic tower defense with intense third-person action.

NFT Integration: We’re building a system where you can own, trade, and upgrade unique digital assets that will enhance your gameplay and carry real-world value.

Multiple Game Modes: From single-player campaigns to co-op missions and competitive PvP battles, OSPTD will offer a variety of gameplay experiences. 

Robies are 26 unique species of intelligent nanobot swarms (A–Z), each representing a letter in the “Robie Alphabet” and serving as the living architects of The Citadel metaverse on the SEI network. Microscopic yet monumental, these NFT-based swarms operate in two core modes: maintaining and upgrading players’ property NFTs (boosting yields, energy, and resource conversion) when idle, or permanently sacrificing themselves in “assembly mode” by slotting into Blueprint NFTs to construct larger assets like Mechs, vehicles, and creatures. With a total supply of 260,000 (10,000 per letter), Robies are the fundamental building blocks and workforce of the ecosystem — tradable, collectible, and infused with the memory of everything they help create, giving the entire Citadel its breathing, evolving soul.
