The Dragons of Arda(Originally The Dragons of Doriath)

What if Morgoth wasn't the creator of all dragons? What if there were dragons that were free of Morgoths control? And what if there were elves that were not immortal, and there was land so far away only Eru knows about it?

A young elleth finds a broken raft of sorts with four strange stones upon it, she unknowingly bring in four dragon eggs into Doriath. When they hatch, the elleth fears the worst, but they are not what they seem.

A young Gondolin guard finds a silver stone within the Encircling Mountains that protects her city, she unsuspectingly becomes the raiser of a dragon.

A Fëanorian, shadowed by her kin-slaying brothers, becomes known when she accidentally brings dragons into her brother's halls.

When disaster strikes the kingdoms, can these young Eldar and the dragons defend it? Or will the kingdoms fall apart?
