I've had this sitting around in my files for a while now just because i felt like the poem/legend/story(?) was missing a piece so today i thought "i'm gonna try to squash in the piece i think would fit" :'D
so clearly quality and art style will be different between a the 2nd row and all the others

1st row is before they hatched
2nd row is them saving themselves or someone/thing saving them from the scariest moment in their lives (Helios was already saved by Devolos just a few minutes before Devolos saved himself)
3rd row when they find their warp stars (i know Spriggian's is out of place here)
4th row is what they look like now

unhatched fire egg and mirror dragons belongs to flightrising
