The Frostnorth Base wasn't so big like the Headquarters, but it was well protected
The Frostnorth Base was inside a Mountain, only the Tower of the Frostnorth Base can seen
Nex steered his Dragon, which was a Ice Dragon, to the top of the Mountain
The rest of the Frostnorths followed behind him

"Can your dragon handle the height?" shouted Nex to Kai
"Of course it can!" shouted back Kai
Kai followed the Frostnorths up the Mountain on their Dragons
After a few seconds, they (The Frostnorths took 5 minutes) reached the top of the Mountain

There was a Landing Pad for Dragons on the top of the Mountain, not far from the Landing Pad was a Warehouse which Kai guessed was where they kept the Dragons
Nex and Michael landed their Dragons first, Butter and Rufus went next, then Emily and Frostz. And at last, the Carrier Dragon
The Frostnorths helped move the Carrier Dragon into the Warehouse with the other Dragons (Though halfway, the Carrier Dragon ran into the Warehouse itself)

The Frostnorths lead the Team into the Frostnorth Base
Mossy and Cookie went last, just before they went in, Mossy saw a something black and purple
Mossy rubbed his eyes, then the thing was gone
"Probably some dust" thought Mossy

Cookie closed the door behind them and Frostz locked the door with a Key with the words "Frostz" carved in it
"Hey, look, it's night already" said Nex as he looked out of the window "Time to go to bed"
Frostz, Emily and Butter showed all of them to their rooms
After a while, all the lights in the Frostnorth Base switched off, and everything went silent
