King Author and all of his people from the round table are in the castle getting ready to enjoy super
One Year later...
I am off on my way
The green knight comes and ask anyone is they want to play a game. No one steps forward util Sir Gawain does.
Finds some castle
The green knight stood there, didn't flinch or move and let Sir Gawain cut his head off. He did make one exception if Gawain did cut his head off then the green knight gets to cut sir Gawain head off in a year.
Gets to leave
You were very loyal expect with keeping that green sash.
After one year Sir Gawain kept his promise and took off to go to the Green Chapel where he would find the Green knight to go through with the promise he kept.
When Sir Gawain was on his way he ran in to some random castle. Here he met this king who said would bring Gawain to where the green knight was on new year. Until then he could stay in their castle and keep his wife company. He also said that they would trade what ever the other one got.
welcome to my castle
The green knight was actually that king. Sir Gawain gave the king everything that he got except for a green sash. So the green knight let him go for showing for showing loyalty.
