Just to mention, it seems that the tweaks to Dwarven attack rates in Worldgen recently have actually paid off.
After many, many worldgens, I have finally witnessed a Dwarf group proactively attacking someone.
And, as luck would have it, in the spirit of fanlore, it was a group of elves that received the attack.
The 55 year Molten Conflict itself was begun by the Elves. But 6 times the Dwarves did take to arms and lead attacks on the dammed friends of nature.
For example the first of these attacks was The Eviscerated Assault, in which 48 dwarves attacked a group of, urm, 0 elves This daring attack concluded in the pillaging of Glitterteachers.
In fact, looking closely at the stats, each of the Dwarf Civ's 6 attacks during The Molten Conflict was against a foe count of zero.
Them Dwarves. Cautious bunch.
On close inspection, it seems that the Dwarves, wily souls that they were, waited until the Elves had suffered massive defeat at the hands of another civ before attacking. The Dwarf attacks are preceded in Legends by hundreds of entries of Elves being hung, impaled and made into gruesome sculptures. After the 6 attacks the small moose population which appears to be all that was left of the Elven civ accepted a peace treaty.
