Onion, named for its partial resemblance to a common onion bulb, interests scientists studying the Zone's flora and fauna. According to studies of the artifact's structure, a significant portion consists of living cells with characteristics of four kingdoms simultaneously.\n\n Professor Salanchak, who is studying the issue, asserts that such an anomalous combination of properties could pose a potential danger to all existing species of living organisms. He also notes that the primary limiting factor for the further spread of the 'new kingdom' is the rapid death of such cells outside the Zone.
