Percy Jackson Guardian of Dragons (a httyd and pjo xover)

Chapter 1

3rd PoV

It was a peaceful night on Dragon Edge the gang were asleep and everything was going--
"HICCUP" screamed an angry Astrid as she marched into Hiccup's hut axe in hand as she stopped in front of Hiccup and stared at him.
"Hey what's up?" asked a very startled and very confused boy.
"WHATS UP! WHATS UP!" Astrid Hofferson was on the verge of tearing his head and stuffing it back on again.
"You space on our date and you have the gall to say WHATS UP!?" she screams at him. As Hiccup realises what has happened he subtly puts a hand behind his back and signals Toothless to discreetly jump from the banister, grab him and fly like Thor is going to hit him with a lightning bolt, (again) that is only if astrid decides to kill Hiccup.
"Well you I was... uh... working on this project and completely forgot that it was... um our uh," as Hiccup tried to make a full sentence he was pretty sure that he wasn't going to be able to wit his way out of this one.
"Could we perhaps reschedule?" Hiccup asks desperate not to lose his best friend, girlfriend and teammate in one day, and probably also his balls.
"Fine we can reschedule for Thorsday next week. Next Week." Astrid had forgiven him thinking he was probably doing something to either help fortify the edge, make something spectacular for her or he just actually completely forgot.

After Astrid 'forgave' Hiccup, well I saw forgave he says 'released anger', they then went for a fly around the edge to see if there were any stray dragons, Vikings or perhaps loose dragon hunters roaming around, what they didn't expect to see was a night fury in a fight with a whispering death. The night fury was being chased towards a herd of yak and was solely focused on trying to evade the enraged dragon hot on its heels while Hiccup and Astrid started heading in that direction Astrid because she didn't want to have a full out dragon fight (again courtesy of Snoutlout) and Hiccup because he had never seen another night fury before.
"We need to stop the whispering death before it destroys the twins yak farm," Hiccup said towards Astrid who was thinking of a way to stop said dragon other than absolutely make a huge enemy.
"What about drawing its attention?" Astrid suggests just before the whispering death screams and pours on even more speed almost catching the night fury in its jaws before the dragon fires a blast of purple plasma into its mouth knocking the dragon out completely.
"Well there's also that option" Hiccup says in a holy-f*cking-sh*t that just happened kind of way. As Hiccup dismounts from his night fury he crouched low and holds out his right hand and slowly walks towards the sleek black beast fully prepared for his hand to be chomped off.
"Hey there, I'm not gonna hurt you I just wanna help" Hiccup soothes the dragon as he walks slowly Astrid now dismounted and in a battle stance but no weapon out afraid if she does that then she'll be single again.
"Hiccup if you die I'll kill you" Astrid states in a way that Hiccup takes as a joke but he fully understands what she means. As Hiccup gets closer to the dragon the night fury bows its head and steps into Hiccups palm accepting the human.
"Well that was easier than I thou--" Hiccup trails off as he notices the pouch and saddle on the dragons back.
"Astrid look it's a tamed night fury!" Astrid leans her head to the side and sees that Hiccup is correct by the saddle and pouch it's definitely been in occupancy of another being.
"Well have a look and see if there is any mention of the owner in there" Astrid suggests gesturing towards the leather pouch securely fastened to the side of the dragons stomach. Hiccup digs his hand into the pouch and feels a singular rolled up parchment. He pulls out the only item inside and studies it carefully turning it over in his hand, making sure to not tear or rip in case it's something important.
"Well read it out Hiccup." Astrid says in a half hearted attempt to be demanding. Hiccup opens the parchment slowly and carefully and begins to read.
"To whomever finds my dragon I have sent her free in hope that she can deliver her children in a safer environment than this war zone. Her name is Blackfire, she is a fully trained and calm night fury roughly the same age as me (20) and is fierce in battle she is already 5 months along but being a dragon you cannot see or tell, I hope that if you have found her to please take care of her for me until I find her again in either this life or the after life. Thank you sincerely Guardian Commander Perseus Anderson Jackson Thorsday 6th." Hiccup finished reading and then quietly re read everything again to make sure he didn't miss anything and surely enough he didn't.
"Well this is dated Thorsday the 6th and that was two months ago" Hiccup said in slight excitement maki Astrid a little on edge as to what was coming next.
"So that means...." Astrid trailed off not knowing what that means.
"It means that this dragon Blackfire should have its children in about oh say three to four days" Hiccup says already jumping up and down ideas and scenarios going through his head about how awesome it would be to have an army of night furies to combat Viggo and his Dragon Hunters.
"Okay that's no terrifying at all" Astrid says in sarcasm as she starts pacing thinking of all the terrible things that's going to happen once the dragons are born, she could already smell the destruction of the twins' hut.
"Okay so if and this is a MASSIVE if. So if we take Blackfire in and help it her give birth what then we can't exactly house however many little baby night furies." Astrid mentions to Hiccup
"There's also the problem of the twins" Hiccup sighs
"The twins" they both say in unison.
"JINX"
"UGH"
