Well, they'd been opened before we got there, so I sort of assumed we'd be close enough to put them under threat for the purpose of my post - if you want, I could edit to include a bit where we move over to the Arbiters upon arriving.
That's kind of a moot point, anyways, considering the whole point here is that the arbiters are at opposite sides of the world, meaning that the two flanking Coalition divisions are a threat to Chandaar and could theoretically cause damage to it, because they are distant from each other and would take time to reach. Kind of like what Tir did, in fact, at Tammar with the SSD.
Anyways, the tunnel thing was getting very confusing, so I thank Ahnk for his help and decision in this matter. Since the Kubaz live on a planet that is constantly bathed in radiation from solar flares, they might have increased defences or measures against radiation leaks in their city, but I'll handle that later - all in all, I might estimate the damage done by the attacks to be comparable to 9/11, except instead of hitting two big buildings rather several smaller ones, with damage spread about a bit.
In fact, now that I think about it, this entire attack bears a great deal of similarity to 9/11, especially if you include things that sort of happened by accident. I'll wait for the explosion to be edited out, then deal with the aftermath of the battle in the city (Including cleanup) and the focus will shift to the lab.
While I'm here, I'd also like to say one of the reasons I haven't spoken much about the effects of the Phage outside the lab is because - to the best of my knowledge - Heir was allowed to RP the Phage as though it were a fleet, or a character, and the spread of a disease was a battle against a conscious enemy. That's confusing enough as it is, and I didn't want to complicate things too much by getting into trouble via posting about Phage without waiting for Heir to take his turn. If this thread finishes before he comes back fully, we might as well move its' effects back to the Wicked thread.
