I haven't worked out my exalting lore for most flights aside from Wind, but in all cases it's going to be something akin to a dragon deciding to become a monk. What your monk duties are depends on the flight and their values and what their societies and deities need from them, but it's universally moving away from your family to participate in a large religious order that is devoted to a particular deity and usually performs specific important jobs for the flight. Exalted dragons are absolutely still alive and can write home or visit home or whatever, they just made a Big Life Decision.
The Windsinger's Exalted have four houses which engage in different jobs that serve their flight and deity, but the task that is of utmost spiritual importance to their order is: The Postal Service.
Freedom of information is
critical to the Windsinger's Exalted. Nearly every region of Sornieth has a scattering of Posts, which are Wind Exalt communes that run delivery services both in-flight and inter-flight, and also provide free medical supplies and skills training to anyone who wants it.
The process of joining the Windsinger's Exalted is effectively an apprenticeship in one or two of several fields, which include but are not limited to:
- Combat training (in which case you will largely be escorting couriers with valuable cargo)
- Wayfinding (helping lost folks get back on track)
- Cartography
- Couriering (mail and package delivery) (difficult and highly respected)
- One of several art forms (it's wind, come on)
...All of which are actually split into multiple disciplines, because depending on a dragon's breed and which area of the world they'll be working in, each field requires different knowledge, abilities, and equipment. Like for example, inter-flight couriering usually involves one or two couriers of an absolutely massive breed (imps, guardians, etc) with the stamina to go far, accompanied by a team of couriers of much smaller breeds who hitch a ride on their back for the long distances and then scatter out to do the individual deliveries at each stop while the big fellas rest. Doing couriering to the underwater settlements in the Sea of a Thousand Currents generally involves an undertide or guardian escort and couriers generally need to be wind- or water-flighted. Etc.
And since The Post is such a massively important service for the whole of Sornieth these days, generally the Windsinger's Exalted enjoy diplomatic immunity wherever they go. It is incredibly taboo to attack or hinder someone displaying the sigil of the Windsinger on their person, and equally taboo to wear such a sigil if you're not one of his Exalted.
I actually have 10 lore dragons (and counting!) who are canonically Exalts of the Windsinger even though they still exist in my lair. They're just funky mail delivery monks and I love them dearly.
