As the more cunning of you might already know, there is a direct correlation between Dragons and Others in the Game of Thrones saga.
There is a plethora of quotes proving that Dragons are magical beings and with their recent return, magic has also returned to the world.
For example, that is what the warlocks said when they tried to steal the dragons from Daenerys Targaryen
At the very same time, we witness the 'rise' of Whitewalkers and wights. I think therefore, it is safe to assume, that the Others are magical creatures, drawn by magic.
Adding to the above that dragons seem so hard (if not impossible) to control and that the Others are marching to the South, is it possible that
the Whitewalker horde is heading to confront the Dragons? And that they maybe want to rest in peace, therefore trying to kill the dragons.
Appreciate any answer, suggestions or legit assumption.
