I think that that those two dragons are actually Kiravel and the demon. According to lore, Kiraveil at the end of his life was killed by a demon. So my theory is that in the next Grah GQ(I here you to do a 2nd grand quest for more evolution matieral for mock unit 7 stars) You and Grahdens are going to have to face the demon which drank Kiravel's blood and to prevent it from reviving itself(due to immortality) Grahdens will probably have to seal the demon within either Ishrion or those two blades hence the name "twilight darkness". (this theory is not real I don't actually know anything based on Grah's 7 star, this guess is based on contextual clues and background information)
