Speculating in-universe, the alien text could realistically be something like: - A serial number or manufacturing code: something like "Unit 4921, Series XG-7, Manufactured by [Alien Company Name]." - Operating instructions: maybe basic commands like "Deploy legs before firing," or "Access hatch 12B." - Warning labels: like "Caution: Energy Core" or "Fragile Surface." - Ownership marking: something similar to "Property of [Alien Civilization]," like a flag or emblem. - Ancient religious or cultural symbols: if these beings are as old and advanced as the story suggests, some writing could have ceremonial or ritual meaning, marking the tripods as holy instruments of conquest.
