You declare that the quaretine is nullified! Nothing is happens, the Crimson Tears are gone. A precise and terrible bio attack. Happens. But no soldier gets ill anymore, the dead are burned. Everything is safe. You hope. The soldiers are a bit concerned about that direct insubordination, but they agree with you, that they're not in danger anymore... Since this disease creeped rapidly in your ranks and kills in a matter of hours, they don't think they have the illness in them.
You send a missive through several channels to the Triumvirate, to tell them that they can resume trade and that the fightings has ended. [4] They reply shortly afterwards, that they're happy with the end of the war. They will resume trade after some weeks, confirming the end of hostilities. They thank you for the good news and wish you a good day.
Your men search the space port to find the vile origins of this bomb. You need to find something... Documents, witnesses, any kind of clue would help!
Also, the sewers are gone unnoticed before, a mistake you won't repeat. You order some of your men to scour the sewers to find hidden weaponry or even rebels.
[4] You certainly find some musquets, bullets and black powder. But nothing more. This place is devoid of all sentient life, only rats are accompanying the search party.
[5] "Hey, look at this!" one of the trackers shout, pulling a large metal shard out of the body of a poor conscript, who was killed by the explosion. As they yank out the gigantic splinter out of him, they can finally read what's written on it : "Property of the House Cr'Tok"
Minutes later, a other group finds some transport documents in an administration office, concerning a large carriage of bombs. Insightful, you find out that there are two more bombs in this space port.
[1] Sadly, most of the documents are censored, so finding out for whom the bombs were is difficult. The thick black ink, who covers several entries are not helping either. But some of your more clever soldiers and yourself try to decypher it...
[?] ...Only to come to the revelation that the bombs are for Aeverys!?
