Into The Snow Covered Woods

Without hesitation, the party of five are greeted by their sixth member. Blaze, a ranger who recently escaped from a town being attacked from a Red Dragon Wyrmling.  They are approached by Derek yet again as his sister's friend's father has been attacked by a pack of something and dropped all his items in the snow-covered woods. (Sounds a bit fishy to me). The party without hesitation agrees to help this boy rather than stop the dragon that's attacking the village. Specifically for this session/episode, it is more in order to help the party understand my battle mechanics as a DM but introduce some VERY key details for the story.
