Viren Was Right. There, I said it.
Now Don't Get Me Wrong...
when it comes to 'who started it?', the humans of TDP are responsible for their fair share of troublemaking.
But I don't think Xadia gets it's fair share of the blame. Let's look at Avizandum.
Apparently, while we only see humans doing something stupid and Xadia retaliating; the Dragon King would pick fights then squash the humans he provoked. The fact glossed over because our boy Zym was sad that his dad's being disrespected. But is it a wonder that some humans feel like they always have a knife to their throat?
Now, personally, I don't like Viren. The guy was manipulative and foolish and just rubbed me the wrong way; and still did up until his death (It was a good death, I'll admit it). But, Viren wasn't completely wrong with his constant spewing about "the threat to humanity".
'But that doesn't count, the humans started it'...yes, and no. See the humans did kill King Avizandum and 'destroyed' his egg. Okay. The Dragon Queen got revenge by ordering a hit on King Harrow and his son. Dept paid, but Janai's forces have had to been gathering since before the assassination. Why? Because getting 'justice' wasn't enough.
The dragons are crossing the border, scaring humans who are just going about their lives in peace. Soren gets the blame for the town being set ablaze, and he should. Corvus warned him not to start he can't finish but why was Pyrrah intimating them? Why is it okay for Pyrrah to just fly around intimating innocent people? Seems like she's picking a fight. Soren gets the blame for starting the whole mess, but he should really get blame for taking some pretty obvious bait.
Then we have these elves attacking Amaya unprovoked. This wasn't retaliation for the outpost on the Xadian side of the border, it hadn't even been discovered and sacked yet.
Little side tangent, why does Amaya get grief for killing Janai's soldiers, when Janai doesn't catch flack for killing Amaya's?
The soldiers didn't abandon the outpost, they were attacked. And they're nowhere to be found. It's not hard to figure out what happened to them.
Now back to why Viren was right in his reasoning, if not his planning. When given the option, why did Janai try to stop Amaya's plan to blow up the Breach?
If she was just protecting their borders, then Janai should have lit the charges herself, as that would cut off the armies best/only known route to Xadia.
Xadia wanted a war. Xadia was starting a war, even though most of the humans wanted no part in it, and Viren was right to be afraid. He's stupid in his actions (we know where Soren got it from) but the signs were there.
