Hieathgur

Hieathgur is the name for the relationship between Hiccup Horrendous Haddock III, Heather, and Dagur the Deranged. It is not a popular pairing within the RotBTD fandom, but it does have a few supporters. As one of the more unorthodox pairings in the fandom, it can be considered a melding of the Hiccther, Dagcup, and Dagther pairings.
