So the next arch as mentioned before will be about the Friendship Games. Returning back in this Arch is your friend from Berk, Hiccup. Astrid is also going to appear, but she's not part of the Harem. I like the idea of Hiccstrid being a thing. I honestly believe they are a great couple. The other riders will also return, but that will be when the Camp Everfree arch starts up. I'll return with this story sometime in May.
Also, we're going to explore more of the past for the OC. If you remember when he got agitated and turned into a Skrill from rage? Well, that's going to happen again, but with different dragons as well.
Also, here's more girls for the Harem. This will be the last of them.
Vignette Valencia
Moon Dancer
Suri Polomare
Upper Crust
Coloratura (Rara)
Blueberry Cake
(Left) Kiwi Lollipop (Right) Supernova Zap
There's a good chance I will add more, but we'll see what happens.
