In the Great Worm Cavern (located in Chapter 3), under the section "Altar", it talks about a couatl who asks the players to seek out the leader of the Great Worm tribe, an evil man named Wormblod. Near the end, it says "If the characters present proof of Wormblod’s death as an offering to the altar, see “Development.”" Except, there's no "Development" section. Is this missing from the original material or...?
See the handout "Eye of the All-Father" under "Chapter 4: The Chosen Path" at the end of part 4.
Thanks for posting this, Mr. Jane! I've added a note to link the text properly in a future patch.
