When we helped Cydwyl with their civil war, they gave us some land as a prize. I recall you saying that this land had been divided when Cydwyl and Methiant split into seperate nations. At which point in history were the two nations one, and why did they split?
Either I ate some words or you read it wrong; no, it is Domain of Donuth that was split. Its first (and last) overlord died and his kids went into mad rush to claim gibs on the throne, and Cydwyls and Methiant banded together to get halves of it for themselves.
Southern went to Methiant (then ruled by Yoe II, I believe), the northern became part of Cydwyl, then ruled by Queen Dogethe. The land that Cidric gave you as prize was the northern half, so entirety of 'Domain of Donuth' now belongs to Methiantese crown.
As for your other question, this is lore thread, not mystery solving thread
Anyway is it just me or does it seem like we're encountering magical stuff/beings/races less than we did back during the days of Luathbas? Though we did recently discover Orcworld so it might just be me being a bit paranoid.
Its human proliferation that causes magical races to hide, and with them the magic hides as well. As humans 'blob' across the continent, even megabeasts, ghosts, demons and fantasy stock dragons will stop showing up.
How many people were killed by the sum total of our plots? What about our wars?
Pretty sure that Yoean dynasty cannot be responsible for more than 200 to 300 thousand deaths so far.
