Larian Studios Forums Divinity 2 - Ego Draconis (English) Help/Tips/Tricks after the battle tower

The battle tower is finally mine but i do not know how to continue ive been doing side quest and distroing flying towers what am to do now
im ok if its a spoiler

Go inside your chamber and look for the teleporter shrine. The rest you should able to figure out by then

i went through the teleporter and distroyed every dragon sheild in fjord except the one surrounding the zepplein still doing that mission but how do you go further in the main quest

There are few things needed for main quest. Fix the zappelin, then you can get to aleroth as zandalor told. Get back to broken valley and kick baal's ass, and you get another main quest item. There a cave behind the waterfall in fjords which also related to main quest. Just explore every inch of land and you eventually complete everything even there non related to main quest. You get to level up as well like this.
