"So what does it say?"
"Death," Words-Like-Flowers tried to keep its tone as neutral as possible. It wouldn't do to appear spooked -- even if it was spooked. Maybe especially if it was spooked.
"A curse upon any who dare enter," said Synchronicity-of-Many-Feet. "That sounds promising. There's something here they wanted to protect."
"They seem to have expected that interpretation, and specifically emphasize that anyone who enters will take nothing away, only... death."
Synchronicity scoffed. "Exactly what I'd expect. Any species sophisticated enough to build structures like this is sophisticated enough to lie about their contents."
"I just..."
Synchronicity waved its upper cilia in an expression of arch skepticism. "Just what?"
"They seem... very earnest," it said finally. Thinking of the skulls. The decomposition sequence that established what the skull actually was. Like an internal carapace, it supposed. A pity it would never get the chance to see one alive... but Sychronicity's expression was evolving into displeasure "I think, at minimum, that they believed that entering this site was certain death."
"And you agree? Even with our superior technology?"
"Superior in some respects, certainly. But we don't know what we don't know. And there's lower-hanging fruit. We could be sequencing DNA. Drilling for petrochemicals -- well, the ones they didn't already use up. This planet has more to offer than a few mysterious sites with ominous glyphs that are trying to warn us off."
"So you admit that's what they're doing. Trying to scare us off."
"Warn us off. I think they're trying to warn everyone off, because there's actually something deadly here!"
"Fireballs-Blooming, plant your explosives."
Words-Like-Flowers bite back further protests. Synchronicity was their leader. Right or wrong, this was its call.
Instead, it subvocalized a prayer it had learned on a distant planet:
May the gods protect those too foolish to protect themselves.
