Hey people

*I am going to bold my questions ><*
I've finished all the quest on Orobas and I've saved Aleroth from the invaders.
I've talked to everyone at Aleroth and I seem to have nothing left to do. the city is still half blocked, can't help with clearing the remains of the invaders...
why?I found and explored the lost tomb.
I saved High Hall's well [But there's a building in the town which I cannot enter,
anyone knows why? it's near the teleportation machine]
Is there a way to make the anti-dragon shields from Orobas' area?Plus, I can't go back to Broken Vally nor to Rivertown George. I am attacked by very strong dragons and fortresses.
And as for my main question:
[color:#FF0000]WHAT NEXT?[/color]
That is it!
Thanks!
P.S:
I have also found the Hall of Echoes, but I need a key to enter it ><
