Bonus points if you ask someone else a question about that event in their world. (Also could serve as a way for your to expand off of your concept if someone asks a question you don't have an answer to…yet.)
Here's some of mine:
While the Terrans are often portrayed as having a large role in the First Galactic War; they did not. In fact, they had a smaller role and most of their support was received by larger or stronger empires.
The Second Galactic War was where they really shined (not really in a good way per-say, while they liberated some worlds they attempted to conquer others for forts or resources which were often looked down upon)
The Third Galactic War, should it happen will see to a larger role if the Terrans are still around. If anyone's still around, rather.
The creation, the in-between and the destruction of the God's Pavilion is the (arguably) rarest event, considering it's happened only once in the amount of times the universe has been recreated and destroyed again and again. It will most likely only happen once, excluding alternate realities and such (which I won't delve into since there are a lot of those.)
The Hezilia Campaign was a battle fought in the SGW, with the two main sides being the Terrans and the Bron. Despite being named Hezilia Campaign, only the last - less than a quarter - bit of the battle took place there. It ended in Bron victory; arguably they only won because they fled onto Hezilia, a planet with hellish conditions that were survivable to them, but to the Terrans it was less than desirable.
The Treaty of Osnein was signed during the SGW on one of the Bron planets; hence its name: Osnein is a Bron country. However, Osnein had little to do with the treaty other than it was the place of signing. The treaty served as a pact between several thousand Empires, and continues to even after SGW. Though only time will tell if it will last. The treaty states that no planet-busting (weaponry destroying entire planets) shall be used, and if they are then the repercussions will be very very big.
