Larian Studios Forums Beyond Divinity (English) Help/Tips/Tricks Act 3 Unsolved Quest

Hi, I hope someone can help, and shall be shocked if the divine Kiya cannot!
I have a couple of unfinished quests in Act 3.
1) Where is the Rannar Traitor?
2) How do you access the locked cave with the text door to the north of the temple area?
Thanks everyone.

Traitor => is on Serrick's Island (eastern island) - in Serrick's Tower.

Locked cave => be patient - you will get a quest to access it later on in the game - main plot.
