While you have been engaged in conversation, the hobgoblins from the camp on the other side of the bridge have rallied and armed themselves, and are now making their way across to support the dragon.
Any of the rest of you who haven't acted yet - Corban and Rurik I believe - may make any stealth checks you make at +10, because the Dragon and Hobgoblins are thoroughly distracted by Xara at the moment. Additionally, should anyone desire to draw first blood, any attacks made right now are at Advantage regardless of the initiative mechanic I was trying to test-pilot!
You are all free to take another round's worth of actions. Corban and Rurik have 2 rounds worth of actions (2 Actions, 2 Moves, 2 Bonus Actions)
