An example here with planet Eridaxnur, during our Challenges Wave 1:
@veryanprime/exode-theorycrafting-eridaxnur-challenge

We ran and completed 19 challenges thanks to all active players during testing season.

This one (Eridaxnur) was part of a first wave of 10, with players receiving four random ones from these ten.

In our December Season, all players will receive the same challenges ; except owners of Ice Worlds and Fire Worlds which will receive a procedural personal generation every time.
