Ok, so I have encountered three exceptional HTTYD fics this last few weeks on ff.net, and I’m going to give them a boost, because they deserve it! All these fics are ongoing so please go read, support with reviews and reblog to signal boost!
1) Black as Night by Wolfie-Dragon (EDIT: Now with correct link! Please reblog this version!)
This is an alternate retelling of httyd1, where a terrible accident in Dragon Training results in Hiccup being permanently blinded. It is a hiccstrid-centric fic, but it is very well written, and the characters are a true treasure to read. It is at a rather critical point of the narrative, so be ready for the only enjoyable stress available to mankind; anticipation. (thanks @hijihoj!)
Apart from this author adorable nom de plum, I must warn you that this is a modern Highschool AU fic, and that the chapters are short and drabble-like, much like ‘How to Hold a Torch’, for reference. However, quite a few things happen for their brevity, and it updates quite regularly. Also of the Hiccstrid persuation, but this is me so no surprise.
Set during RTTE, this is a very sweet little fic about - who else - hiccstrid finally getting closer to being - what else - hiccstrid. It is adorable and well written, and I can’t wait for another update. I have seen it floating around on tumblr, so the author is also a tumbro.
Not in the numbered list because this fic is on the … hotter side. I’m also pretty sure that everyone has read it; but just in case. A warning needed with this fic; Ecoutez writes amazing sexual tension. You can feel it peeling your screen. So have some ice-water nearby! Some fics in her same headcanon universe are also available on ff.net on her account.
