I'm a thwarter.
Sir Conrad returns to studying the map intently. His eyes flash red briefly and a smile crosses his dark features. He calls the others over. "A most valuable find milady. There is a bit more to this than meets the eye directly. This is a horde directed by the cult of Tiamat. My order hunts down the evils of the world and the spawn of Hell are my particular area of expertise. Tiamat is not just a queen of dragons but was also ruler of the entryway of Avernus. Some believe this is mere myth, others that she was so only in the past due to a pact with the lord of all devils which is now completed, others that she was and is a Lord of the Nine herself, one of the archdevils. She is intelligent, powerful, ambitious, and devious. A dangerous foe to be respected and opposed." He pauses.
"The horde here is under the overall rule of the cult, the hobgoblins and soldiers may not know it but they work for an unspecified motive of the cult's. The horde is led by four wyrmlords. Koth, Stormcaller, Saarrvith, and Kharn. It is not just hobgoblins but dozens of tribes of goblins, bugbears, and ogres as well. They are gathering from across the Wyrmsmoke mountains. We know they have hell hounds but she is also known for the abishai, devils mixed with the power of dragons. I would not be surprised to see such creatures here at some point.
The green dragon I fought today is named Ozyrrendion. He was to fly across the river and terrorize the population of Drellin's Ferry, holding it while the Horde crossed the river, Koth was going to lead the assault. He is but one of several dragons who serve "The Hand".
Their drive looks straightforward, moving from west to east. It will drive straight through the Ferry and on into the heart of the countryside. But note that wyrmlord Saarvith is not with Kharn and the massing horde, he is up north where they suspect lizard folk to be." Sir Conrad's gauntlet hand gestures to the swamps on the top middle of the map.
"War is coming, but that is but a lie in the form of a big glaring, distracting truth. Everybody will be focusing on the threat of slavery, death, and conquest of the land. What I want to know is why the cult wants to drive through here. The cult does not care about giving tillable land to goblinoid tribes. I want to know their true purpose. And thwart it."
