I just realised that in all my hours of playing...i never actually found out who summons the dragons. Delphene: "dragons aren't just coming back, they're coming back to life." can someone tell me why? I know Alduin is the one who brings the lesser dragons back...but where did alduin come from?

Seriously? All I can say is complete the MQ and your question is answered.

Yeah, noob question i know. It's been years since i have done the MQ. Was just wondering if someone could give me a quick

answer.

I also meant to ask, how come Alduin attacked Helgen? Forgot that bit, sorry!

I could have sworn I was in General Discussion

The ancient Nords used an Elder Scroll to cast Alduin forward in time. He re-appears shortly before the start of the game, and first reveals himself during the Helgen scene. He doesn't really have a specific reason to be there, but it is quite close to the Throat of the World, where he would have re-appeared. He may also have been able to tell that both a Dragonborn and a would-be Greybeard were there at the time.

Alduin has the power to raise slain dragons from the dead. Hence, the Dragonborn is the ultimate dragonslayer - he absorbs the souls of dragons, preventing them from being raised by Alduin. Note that the Dragonborn doesn't absorb Alduin's soul, suggesting he may be back again, one day.
