So this is a crossover fic between Homestuck and the Mortal Instruments series and an indulgence fic for my two rare pairs. Sorry for the bad summary..
Dave and Dirk are three years apart in age, Dave 16 and Dirk 19. They both see the creatures, the ones Dirk calls Demons. They also see the people dressed in black, battling these creatures in crowded streets where nobody seems to see them. But then one of the figures dressed in black, with his odd eyes and lisp, notices them. Dirk knows things that Dave doesn't. He knows what's going on, he knows what these creatures are and who the people in black are. But Dave will find out soon too when they're taken to the nearby institute and trained as Shadow Hunter. Dave learns of his parent, the downworlders, and demons. He finds himself yearning for Sollux and Dirk finds himself entranced by the young Vampire Kankri Vantas, meanwhile, Kankris brother Karkat is caught up with a certain warlock, John Egbert.
