Stuck in beginning of game...

[Rhorhan]

Hey, I started playing this campaign, but now I'm truly stuck. I entered the Southern Entrance, defeated all creeps in surrounding area, but now I can't advance. There is a massive ruined gate that obviously needs to be opened somehow, but I I can't find any clues. I tried inspecting anything near area but all came up blank. There is a smaller ruined gate just below it, but "fallen rubble has made this gate impossible to open".
Can someone please help or suggest something...

Inspect bookshelves for hints. What you are looking for is inspecting a blue circle near the Goblin merchant, and then using the item you obtain on the firepot behind the Skeleton Warlord.

You are not supposed to Inspect "anything, anywhere". The Inspect ability tooltip explains that Bookshelves and Blue Circles are the core places that can be interacted with and the ones that provide information. One of the Bookshelves states that a key was dropped in a Firepit. Earlier you acquire an item from a puzzle. Piece it all together.
