I believe you've mentioned previously that the Dunewyrms have allied with both the Chroma and the Kuros against each other at various points in history depending on the state of the balance at the time. But, have the Kuros and Chroma ever allied and joined forces against the Dunewyrms?
MOD: The Chroma and Kuros alliances usually never work, since there’s just too much bad blood between them. The Dunewyrms have pissed them both off enough in the past for them to try and team up to teach them a thing or two, which prompted the treaties drawn up that Titus went against.
This particular war is known as ‘The Two Season War,’ which is notoriously short for dragons of any species. Since dragons do have notoriously long lifespans, entire generations can be born and hatched and have their first flight (which is about 80-100 years) until wars end. The Two Season War is one that’s often brought up by the Kuros/Chroma to the Dunewyrms, who were quick to call for peace talks. The Dunewyrms stand for balance above all things, and were willing to give up a few territories (small in comparison to their main kingdom, which is the most important) in exchange for peace and balance to be restored.
Other than this, beyond small skirmishes when someone steps into places they’re not supposed to for too long, the Kuros and Chroma hate each other enough that it’s difficult unless it’s an individual-to-individual basis. Generally, the Dunewyrms are respected enough, though all other species of dragons like to call the Dunewyrms cowards since they aren’t as active in wars unless it looks like balance is going to be shaken up a bit.
