Oh yes. This is perfect. THIS IS THE ANSWER TO ALL THE RIDDLES.

Spoiler!

The Imperial Remnants want/are using Mandalore as a staging ground.

Through the show we hear everyone refer to Mandalore as a "wasteland" or "cursed" implying few, if any, people frequent the planet. In s2e2 we hear Din say immediately after entering the atmosphere that "the fusion bombs disrupted the magnetic field around the planet" and that they were essentially "cut off from the rest of the galaxy." And finally, in s2e3 dozens of Imp fighters seemingly appear out of nowhere, heavily implying either a local base or destroyer in the area.

All this sets Mandalore up as a perfect secret/concealed base for the Imps. Also, having the Imps on Mandalor would be an easy way to push the plot forward, and ensure a reason to bust out the Mythosaur....
