I think apparent avenues to proceed are:
1) return to Nerisella and find out what else is needed for the ritual
2) Return to confront the Woad and or see if the dragon left loot
3) follow up on Dayereth's findings and try to investigate the kruthik's nest, or the submerged tunnel at the owlbears den/ explore the sunless realm.
4) travel to Little boy following up on Nadderesh's dream
5) Travel to Brix to follow up on the hints of Bood being a doppleganger and the wizard's seizing control of the city.
6) Travel to Shattered Bridge to lend aid against stiches.
7) Investigate the dragons near Aerandis's home
8) Try to chase down the gable's crossings dragon
9) Other.
Wow lots going on. A little guidance on how to prepare would be helpful.
