Flashback Orbs & Desert Treasures

Alright, so previously I've mentioned three flashback orbs that will be available, dealing with Zhamla finding his first card, Young Dad meeting equally young Ivy and Charlotte, and Charlotte speaking to the winter elder after saving Santa Fae from the legendary Goblin King.

Since then we've decided to add two more such orbs, one that details how the Black Ferrets gang came to be (which yes, weirdly enough involves professor Mandrake!), and one that features Professor Pine and Tannie working on the weapons they used when trying to defeat Zhamla.

The portraits for the mentioned events have been made, but now they all need expressions to fit what's going on:

Meanwhile, a different piece remaining before the desert is fully ready for the stable patch is a set of treasure maps. These will be given to you by the archaeologist Finder, who is busy doing other things and cannot dig at so many places at the same time. So it's up to you to find and bring back these ancient treasures to the archaeologist's collection:

Perhaps by doing so, you might even get some sort of reward?!

As for the maps themselves, they too need to be made. And since you're here and have read this far, you can have a look at them before anyone else:

Can you figure out where to look for the treasure? :)
