The Infinities: The Tower of Beginnings

The Infinities are mysterious dungeons which have been sprouting up in the world of Mystari.
They hold a great amount of resources which help thriving communities grow and prosper.
Many humans and humanoid-creatures alike go into the Infinities and become Explorers with dreams and aspirations.
Explorers become ageless through the stories told of their exploits and some end up being legends and then transcend into myths.
The first time a normal person enters an Infinity they are blessed with two powers.
One based on their own personality that will warp and change as they grow and develop as a person.
While the other one is based on their strongest wish when they enter.
Those who survive weave a magnificent tale of adventure. (And romance rarely.)
But, the Infinities are a dangerous place where many try to make it rich or die trying.
