Throne and Liberty Investigate the Chief Terror Bird Nest
Chapter 4: The Terrific Trio of Carmine Forest Exploration Codex Entry

Inside the nest that Robert asked you to investigate, there was a large Terror Bird corpse, a broken blade plunged deep within it. Could it be the sword of someone who had tried to protect the carriages? The only clue as to its wielder is an unusual pattern engraved upon the blade. Robert might know more about the person who wielded this sword.
