The Plan
After inciting the orcs' morale with the best speech he could make and several drums worth of meads, Tristan gathered a few people inside the keep for a briefing in the middle of the night.
Karra and the two Orc Champions were surely invited as they were the higher-ups of the orcs. There were also Barry, Seth, Herrera and his sister Layla that came from his side. He also didn't forget the two under his Blood Seal influence, Borin and Astrid.
The briefing began with Astrid blurting out the details of the barbarian forces that would attack the fort tomorrow. Everyone who attended the briefing quickly perked their ears, especially Tristan as the commander of the upcoming battle. They were afraid that they would miss the information if they didn't listen attentively.
The attack would be launched by three tribes. All led by veteran captains that weren't worse than Astrid. Each of them brought more than five hundred barbarian warriors to this battle.
