Where to start? If you have ever played Main/Ascended/New Grounds/Origins... The Idea is pretty much the same. First off. The Quantum reset every three months. Each era has something different. Different Goals/Illnesses ect. I might as well post what it says on the log in page. ^_^
QUANTUM ERA 33 PeasantVille
No - Not PleasantVille.
This quantumverse is very slow to develop.
It is closer to Medieval than anything else.
Everyone fights. Everyone dies.
And peasants are treated like currency (you can even 'store' them for later!).
And rumor of a midas plague spreads !
You expect this era to be very....messy.
TO ARMS!!
THIS IS ONE OF BUT MANY POSSIBLE QUANTUM REALITIES.
EVERY 3 EARTH MONTHS OR SO, A NEW REALITY IS EXPLORED, COLLAPSING THE LAST REALITY AND LEAVING ONLY THE WRITTEN RECORDS OF THE GREAT WARRIORS OF ALL RACES.
WHO WILL RULE THIS REALITY? WILL THEY RULE OTHER REALITIES AS WELL? OR WILL THE POWERFUL IN ONE REALITY BECOME THE WEAK IN OTHERS?
ONLY TIME, EXPLORING, LIVING AND BATTLING ACROSS ALL QUANTUM REALITIES WILL REVEAL THESE ANSWERS...
That being said you could take it as a battle to the death or just How ever you want to see it!

Next Question!
Pregatory?
I always thought it was spelled Purgatory... xD But for argument sake ill go with your spelling.
I have only used Pregatory a few times (My army is too large to go in now a days) But basically. You can switch over to that realm(I think its only in main?) Anyways all your AT's are turned into naq. You can only hit or be hit a limited amount of times. (Last time i checked anyways) it takes about a weeks worth of AT's saved up to get back to normal space....
Last question.
Weapons!

Obviously you train your units. After training you go to Armory. (Navi:

You scroll down. On the left side you can see what units you have trained. (

To the right you can Armor your Units. (

So yeah hope this helped some? O.o
