Based on Day 2 of the Inktober challenge. I do not own RoTG or GoC. I also do not own the works of Robert Frost.
They called it a Golden Age. Jack just snorts, and stretches out a slender finger, and freezes the inkwell solid. He's Tall, today, as big as he can make himself. And Mark, and Eddie, and Izzie can all see him, and call him Mis-ter Frost, all nice and proper.
They cannot see Jack Frost though. Cannot see him when he's Small, or not quite Tall enough. Can only see him when he's Mis-ter Frost. And that hurts, stings in a way he cannot soothe.
The papers call it a "Golden Age" that they're living in, and Jack is certain that they are not- not nearly happy enough, not nearly bright enough. He's not quite sure what sort of age they're in, only that it is not Golden. Because nothing gold can stay, and gold faded a long, long time ago.
He can hear boots tramping up the stairs, and he smiles. He pulls out a letter, with such words like "Marriage" and "Volcano" and other words, all written so very Tall. This will make for a very fine tale. And it's worth not being seen sometimes, if it means telling it.
According to William Joyce, Jack can be older or younger (to a point) at will. He also made friends with a number of famous people during the Belle Epoch (roughly 1783 (the earliest possible date) to 1914). The Belle Epoch was called a Golden Age - something I think is no coincidence.
