Midgardsormr and his children [Spoilers]

[HumsterMKX]

So, seven children... Fafnir, Nidhogg, Tiamat, Ouryu, Vrtra, Bahamut, Shinryu? Just as well, there are only two in Eorzea. If Bahamut still counts as one, that leaves the very, very, very likely Nidhogg.

Also, do we think there's a mommy (Wyrm Queen) in the picture, or did he(it) lay all those fertilized eggs himself?

From the looks of it, he probably willed them into existence.
