To the north, the Emerald Sword clan of the Dinacoli is an old foe. You have fought with them many times and you are feuding with them now — they have killed kinfolk and you have not been paid in blood or cows for those deaths.
The Dinacoli betrayed Sartar when the Lunar Empire invaded. They embraced the rule of the Lunar Empire and grew fat and rich. They prospered whilst you suffered from Imperial rule. Many in the clan say that you should make the Emerald Sword pay for your sufferings and take back from them what you lost.
