so going by Inquisitors questions in E5S2 of Anthem, we can all agree that the Eternity Lance Explosion happened very recently, right?
--- Increased orbital security overall and the security checks, especially regarding Cavalon Empire (presumably after the Krayta Siege)
--- Questioning about "General Sigurds survivings loyalists", implying Sigurd had already been unmasked as a traitor to the Empire long enough for it to reach Krayta some time ago, which happened during the charging of EL, BUT it was recent enough that they are still actively seeking suspects
--- Questioning about "taking, planning or assisting any hostile action against Saurok Dynasty" (presumably after what Qiri did and what happened on Sothorys because of it)
--- Constant mentions of there being tense, turbulent times
--- Inquisitor questioning the fact that Ziggy, as a Woog, doesn't know why they are being asked all that, meaning that if his family still talked with him he WOULD'VE known by now
BUT none of the crew have any idea about ANY of it?
My guess is that the Krayta Siege AND the Explosion happened somewhere between Ziggy's birthday and them landing on Krayta, which took them almost a month/about 30 days
I'd assume that, outside of the Empire and Dynasty's military, people wouldn't know yet or, in case of Solar Federation, care.
Add to that Ziggy was first busy trying to crack the M3G case, then he had to redact Rhapsody's records, THEN him probably avoiding anything on Dynasty after failing to contact his family and no wonder they know nothing - if their research guy who knows the topic the best didn't say anything is happening there is no reason to assume otherwise
And considering that between the Siege and Explosion themselves was about 16-18 days...
The ashes are still falling, still hot - no wonder they got burns from poking them
