In the Rewrite au, it's basically a tie in to a rewrite of Httyd 3, where pretty much everything changes, including the fact that Toothless is the last one, cause he isn't in the rewrite. The Httyd 3 rewrite has a change where after a good amount of the Night fury species gets killed by Grimmel, the rest go into the 'Hidden world' which in the rewrite, is a giant hollowed mountain where the only entrance is through the water, like a beaver den.

The Hidden world is only home to Night furies and Light furies, who at this point, have merged together and created a symbiotic relationship. Toothless follows the Light fury into the nest, and sees Night furies and Light furies living together, even encountering a baby Nightlight.
