Larian Studios Forums Divinity 2 - Ego Draconis (English) Help/Tips/Tricks Some unfinished quests in Fjords

I'm trying to wrap things up. So a few questions I have not been able to solve:

1) I need to get something from the boat in the tree on sentinal island. When / how do I get there ?

2) I stil haven't found Ragon, Where's this Grotto ?

>>> found him. He's in a cave left of the bunker...

3) I need to find the book for Barbatos, but haven't found it yet...

>>> found it. It's in the cave where the goblin beholder asks to get a translator

4) For the ancient marinier quest I need to get Ulfmar's spellbook. I have no clue where to start?

>>> I think this is the same quest as 1). My guess is I should have done it before going to
the Fjords?

5) Should I go to Aleroth before or after The Hall of echoes? Im guessing before.... ?

TIA
