Delay your arrival at the Feast and take a walk around the grounds

The bastard Northerners and the twat of a King could wait. Although cold, it was a relatively decent evening, and you had never seen Winterfell before. Pulling on a warmer winter coat, you headed out into the courtyard. It was quiet, with many of attendants and guests already in the Great Hall. You could hear the bustle, the voices and the music blaring already. It made you relieved to be away from it.

The guards you passed either shied away from you, or stared with utter vehemence as you passed. No respect. You could imagine what they were thinking. "There goes the Kingslayer." The title that you hated more with each passing year. If they only knew.

You were now wandering aimlessly. The Godswood was nearby, and Winterfell's Godswood was said to be miraculously beautiful, even by the standards of Southern gardens. Or, you could explore the castle proper. Ensure everything is safe, and that there are no potential avenues for threats.
