Nathirap and Eareb are goblin brothers found in front of Willy's House on Lanilor Lane in Aleroth during the events of Divinity II: Flames of Vengeance. They are warrior outcasts formerly known as the "Brothers of the Spear," who relocated to Aleroth to live what Eareb calls "a civilised life away from the tribes and backward shamans."
They were forced to surrender their weapons and take a vow to live like humans upon arriving in Aleroth. To this end, they have tried experiencing all Aleroth has to offer, including visiting Madame Eve's regularly, although they don't quite seem to understand what occurs there (see Madam Eve's Charter).
The brothers have a strong dislike of the Black Ring and would like nothing more than to fight alongside the human Champions, but they have been shunned by Captain Aquila. They offer the quest Brothers in Arms, seeking your aid to be accepted.
