Skylanders: Darkest Hour (Arc)

The Darkest Hour approaches... are YOU afraid of the Dark? - Blurb for Darkest Hour from the author's DeviantArt account.
Skylanders: Darkest Hour is the official name of the three-book arc written by Undead Prowess (formerly known as Numbuh 94) on Fanfiction.Net. It consists of three books, Skylanders: Rise of the Dragon King, Skylanders: Swap Force, and Skylanders: The Book of Heroes. It shows how the Skylanders fight and defeat a great new enemy.

Main article: Skylanders: Rise of the Dragon King
Rise of the Dragon King explains Deu Sol's rise and defeat, as well as the eight elemental dragon pairs. These consist of:
*Ace & Thor
*Geo (Skylanders Character) & Boulder
*Pyro & Blaze
*Agua & Aquamarine
*Corpse & Cadaver
*Bio & Feuille
*Ala & Kaz
*Techna & Blade (Skylanders Character)
Deu Sol himself was once a Sun Dragon, or Fire elemental being, but after being corrupted and changed, he became an Undead elemental being. He is classified as an Undead being.
He is also mentioned by Lone Nexus to have incapacitated Sundrake, the Ninth Generation Skylanders' leader somehow. 
The Skylanders, slowly but surely, fight their way against Deu Sol, beating all of his legendary eight dragon pairs, until they finally face him. Along the way, the Skylanders discover some secrets about themselves--some wonderful, some shocking--and discover the true meaning of teamwork and loyalty, life and love, and everything else in between.
===Spinoffs===
So far, Skylanders: Rise of the Dragon King has three spin-offs, The Most Frightening of Rides, My Story (Hex's Entry), and Snow Quest. The Most Frightening of Rides explains Fright Rider's history as shown in Darkest Hour, Snow Quest shows that of Chill's (also as shown in Darkest Hour), and My Story (Hex's Entry) is Hex's history, as mentioned in Darkest Hour.
