In the center of The Howl and north of Faction Town: The Launchpad is a settlement high up on a hill. The Vault Hunter’s Guide to Kairos: The Fadefields is hanging on a shelter.

The Vault Hunter’s Guide: The Fields are Alive is attached to a pole in a small settlement by the main road between Synthetic Nave and The Killing Floors in the Dissected Plateau region.

The Vault Hunter’s Guide: Escape is probably the first collectible you will find when coming into the city from Lopside into the Carcadia District.
