A fictional series of objects based on three separate classes, Safe, Euclid, and Keter. Safe classes are objects who aren't considered dangerous or deadly in any way. Euclid classes are unpredictable and can be dangerous when not watched. Lastly, Keter classes are dangerous to man and could possibly be dangerous enough to obliterate humanity. There is a range of 3000 different objects and each one is unique in its own way. Some of these objects are unknown but others have been fully released.
