Tonby and Larsie reach temple of Savras and split there.
Tonby talk to an acolyte about the books and chult creatures.
You may not find much of the information you seek, I'm afraid. Merzo used to be center of culture and all knowledge and books were concentrated there until it was destroyed during spellplague and all books gone. The only books we have comes from main continent. And the only book listing types of creatures I recall is book on celestials, I'm afraid. Talk to older locals for history of Chult and jungle guides for creatures that live in Chult.
Zitembe do not deny his ability to locate the object as you asked, he just can't believe it could be located in Chult. He wouldn't initially want to believe you and would question our source of information
Razira look at Elster as if he is not in his mind: Out of the city? How do you mean that? word by word you realize that locals are reflecting to the districts outside the city walls as outer city (still a city). When you explain that she would need to move to Old city, she is very much upset - it would basically mean she becomes a real criminal and need to learn to live among criminal. Still better than die. I would still like to try my chances with the prince first.
As you talk a Chultain woman well dress comes in accompanied by a retinue of aides and guards. Ekene-Afa whispers Razira ex-gladiator, prince of ... well basically any gear an adventure may want going into the chult, not just weapons.
