Solution:

After a bit of searching for the names of all of the people in the pictures, the only obvious connection between all of them is that airports in the USA are named after each of them. This might have been a somewhat difficult connection to make, but there was a slight hint in the title of the ITH quiz - A Chunk of Fancy is a combination of two common idioms - "Chunk of Change" and "Flight of Fancy".

Flight obviously indicates that you should be looking for something related to flights -> airports. The change portion comes a bit later. A list of all of the airports is given by Chour here. After placing them all on a map, you get this, which is a closed shape, that looks somewhat like a triangle. Unfortunately it's pretty much impossible to find a combination of different airports to make an exact shape, but I did my best. This is where the 2nd part of the title comes into play - "Chang" is a hint for the shape you see at the end - Greek letter delta is commonly used to indicate change.

The answer is Delta

It's been over a year since you and your friends last forayed into the Temple of Steamgifts. You miss the excitement and mystery of adventure - not even finding the Stick of Truth could quench your thirst. Well, today is turning out to be your lucky day. A package arrived in the mail today with no return address. Inside, you find a walkie-talkie and a letter:

"I've received word that a loud grinding sound was heard from within the Temple of Steamgifts recently. As the first ones to completely map the area, I thought I'd warn you that several teams of treasure hunters have already embarked to the site. Perhaps there is more treasure to be found."

It looks like it's about time to get off your butt! A new journey is about to start.
