Secret Orders: The Celestial Brotherhood

So you might come across some order in its public life or even get some legitimate work with some agents. You could even be working in an organisation that in secret has horrible agendas for a while before you join the higher ranks and hear about the ordered schemes. You could discover documents or witness that order is not what it seems. Perhaps a party will join to keep an eye on them or learn their secrets to destroy or reform them. A new character might start with an order patron and take years to discover the real order purpose.

My next frpg I will use a bunch of these
Some guilds, knight orders, sisterhood and secret cults in future

Obviously, these guys are toxic jerks who put forcewall ceilings on important wizard careers. I envisage them starting as a loved adventurer club then ramp up their true proposes and plans over time. I expect eventually their secret symbols will be known and the party will recognise wizard members by jewellery or tattoos

The Celestial Brotherhood

Public Goals 
To promote the benefits of manly wizardry to the commoners and nobility
Create public works, monuments and improvements to aid the welfare of commoners
Wizards can meet to get discus community wellbeing
Real Goals 
Have weekly secret meetings then drunken binges and singing and feasting
To conquer the world one kingdom at a time
To operate in secret so the common scum and idiot nobles never know
Keep women out of wizardry and even literacy is too good for them
Just summon or make better lovers if you need them, until then don't bother with them 
Leaders 
A great council of the 5 greatest wizards rule and occasionally there is a deadly duel to replace one (one is a lich unknown to all). Each kingdom has a lesser council of 5 
Members 
Suitable members are questioned in secret to see if they have the right aspirations. Some of these questions may be done secretly by different members so prospective wizard won't even know. Many are in academia or just regional backwoods wizards. A secret initiation ritual involves a test of your resolve and some who fail are killed if seen as too dangerous. Most of lesser ranks under name level don't even know about secrets
Followers 
These are commoners and student wizards who join in hopes of being noticed or getting spells. Some masters give apprentices extra credit for working with the order. Others help the order because of their good deeds and charity
