After Hiccup saved him, Viggo lived on Dragon's Edge, because of that, he was made a dragon rider, with his Skrill as his dragon of choice. The other riders admired how he was able to tame such a dragon. . .

He had gotten to know most of the dragon riders, and grew to respect them all in. . . Very different ways. Some of them he respected more than others. . . A lot more than others.
