Game of Thrones Thought: Dragonglass
Just more random thoughts about the Game of Thrones. Now-Maester Samwell Tarly figures out how to produce Dragonglass in quantities. Heck, maybe Sam’s hometown has Obsidian deposits from which weapons can be forged.
And guess who comes to the rescue when Jon Show and company are cornered by the White Walkers? Yup, Sam the Slayer. Well, he just provides Dragonglass tipped arrows to archers who lay down an escape route for Jon.
