A free incremental RPG you can play entirely offline. No ads, no paywall, and every goal in the game is reachable without spending a cent. The world's eight elemental forces were once held apart. Now they are bleeding together, and everything is changing. You are a Cataloguer: a licensed scholar sent into the saturated zones to document what lives there. Encounter creatures, record them, and fill the Manifest, one species at a time. The more you catalogue, the more the world opens up, and the closer you come to the thing nobody wants to talk about: why everything is falling apart. If you've always wanted to play a uniquely idle monster collecting adventure with the patience of a nature documentary and the wit of a dungeon crawl, this is your chance. Explore portals, return to new species and new regions, and watch the Manifest fill in like a field journal. WHAT YOU'LL FIND • Over 4,000 creatures to find, fight, and catalogue. Each holds a small piece of the overall narrative. • Over 300 classes to equip and level up. Send your hero into elemental portals and take control as battles unfold. • Offline progression that unlocks early and never stops: your hero keeps earning and your disciples keep hunting while the app is closed. • Every portal is graded. The threat ratings are, unfortunately, accurate. • 16 narrators bring the world alive through their lost dossiers. Sixteen cataloguers came before you and its on you to find out why they stopped writing. • Deep progression: level classes, raise disciples, study at the university, upgrade your guild license, master insignias, power up skills, and more. • Rare enemy variants, an ever-expanding ladder of achievements, and Game Center leaderboards (purely optional). FAIR BY DESIGN The whole game is offline, free, and ad-free. The optional purchases are purely cosmetics that support a solo, part-time developer. I'm an incremental game fan who got bored waiting for the next one to drop. Made by one person as a part-time passion project. Thank you for giving it a shot!
