Anderus actually didn't know Tessa's name or the fact she was a prisoner inside the castle,
he merely understood that talking to the local Lord maybe helpful, and besides he felt with his guts that he should check this castle and he always trusted his instincts.
He moved quickly and silently towards the castle, suddenly he stopped, he smelled blood. Anderus followed the smell and found a bunch of bandits lying on the ground with their heads crushed, Anderus understood from the picture that whatever or whoever killed those men was very strong!
"I must hurry!" Said Anderus to himself and continued his search.
After few minutes he saw the young priestess from the corner of the street and the huge armed warrior standing near her, he didn't know whether the warrior was friendly or not but he did understand that probably he is the one who killed those men in the alley, Anderus took out both of his scimitars and jumped between the young priestess and the huge warrior, "Be careful, he is dangerous!" he shouted to Tessa while facing Durus with his weapons in a ready position, Anderus understood of course that the warrior is very strong, but he was obligated to protect the young priestess, and besides he trusted his speed and martial training.
"Who are you and what do you want from the young lady?" Asked Anderus while remaining in a battle ready position between the warrior and the priestess, ready to strike at the first sign of hostility.
