For our purposes we can't take anything for granted as a child with an abusive parent who will take any excuse to beat us half to death can't. For all we know wearing Purple shorts might set them off. Or perhaps a mentally ill abusive parent for whom reality operates on different rules.
I trust that Snowfire isn't going to be as ridiculous as the above example. But they're writing a species whose rules we as players aren't able to figure out by Game master fiat of not seeing the revalent information - so in character we have to act as if they're a dangerously erratic force we can't predict or stay within the rules of. Because we can't.
I'm going to have to question where this is coming from. The Shiplords gave you the Directives. Yes, you couldn't have predicted their reaction to how Practice was used in the Second Battle of Sol, but Speaking was so new at that point that there was no ability to look into how it might be reacted to - especially with Project Insight offline.
But this discussion isn't under a spoiler blanket like the grander Shiplord intentions are. The Shiplord Tribute Fleet detected something during the Second Battle of Sol that released the
Medicament to involve itself.
Given that my attempts to lead to people to the right answer have apparently backfired so horribly that I'm coming across as taunting or abusive, I might as well just say it.
That was the point at which they detected Practice. Its use, and its presence. That is what cleared the
Medicament to involve itself. And there were couriers launched then, but the Tribute Fleet was well inside of the SEZ at that point and none of them made it out.
Why Practice caused this reaction? That I won't tell you. But it was the cause. Nothing more. And nothing less, either.
Why the Shiplords aborted the Tribute fight on those aliens I did an interlude about? They'd analysed the enemy forces, their weapons, and could see that they'd decided to run instead of fight. They failed the test that the Tribute Fleets embody, and were trying to escape from it. So the Tribute Fleet launched a kinetic bombardment.
To be very, very clear. I do not condone what the Shiplords are doing. I am not trying to present them as nice. They have built an empire atop the deaths of trillions - and that's probably understating. They believe they're justified.
That doesn't make them right.
