Any recommendations for Hiccup Runaway fanfics?

I've been reading several Hiccup Runaway fanfics, but I've become absolutely obsessed with one in particular—well, actually, two, but they're by the same author. The problem is, I've read both twice, and I really want to wait for more chapters before rereading them, but I haven't found anything as good as those two fanfics in particular. Their titles are "Occupational Hazards" and "The Night Rider," both by cestialdemon9909. The first one is about a cold-hearted but kind-hearted Hiccup, good at pretending he's a stranger to his home island while he looks for a way to support Berk against Drago's threat. I won't give away too much, but that part is more or less what I'm looking for: a Runaway where he returns to Berk as a covert ally. Since this is more of a subgenre within a subgenre, it's difficult to find. If anyone could help me and give me a good recommendation, I would really appreciate it.

P.S. The second one has a very different plot. It's about a Hiccup trapped by Rider, who's trying to recover the gold Hiccup stole, and a Stoick allied with him to find what he believes is the trail of his lost son. It's intriguing because he has no idea that the masked dragon rider is actually his son. If anyone wants to read it, it's very good.
