When you visit the Vessel Village for the first time you'll meet Wufan again, who you first met in the Miasma Forest. She'll greet you with great hostility, until the Medium interrupts her and welcomes you more warmly despite Wufan's irritation. Eventually Wufan will be called away and the Medium and your Guild will be left alone to talk. The Medium will inquire about the world outside the Ravine, you're free to answer to truthfully or keep quiet, the end result is the same. However if you answer truthfully the Medium will be over joyed to hear such a fascinating tale as she was certain she was the only human around up until this point. Wufan interrupts angrily and tells you the story of the Titan and how the humans fled from the battle leaving the Vessels and other races to face the Titan
