In the HTTYD aftermath, Hiccup and Astrid are known to have two children. Toothless and the Light Fury have three. This means that there is an uneven amount of humans and dragons to go around, and there will be a left-alone Night Light. But what if that wasn't the case? What if Hiccup and Astrid had had another child, a third child? Why wasn't she featured in the Homecoming scene? What is so secretive about this child's life? Join this epic adventure, HTTYD 4, as we reunite the next generation of dragon riders: Zephyr, Nuffink, and Zella. By Pepper9990
