Larian Studios Forums Divinity II The Dragon Knight Saga / Flames of Vengeance (English) Divinity II - Flames of Vengeance Viper leggings

I can't find a key or button to open the sewers in the crows nest.
Or is there a second entrance in there?
The leggings are the last part needed to complete my set

I found it somehow.
i had to speak to the beggar i think.
