Very quick notes.. as I noted before, if the nobility outright don't like them, their function as desired courtesans and companions to the aristocracy doesn't super work, that part should be edited out.
Noble posturing, often out of spite that the Order even dares claim ties to the Bearded ones.
They're after more a sponsored imperial order than anything, the nobility aren't super likely to see themselves being infringed on. The bit with senatorial maneuvering is fine, as the bureaucracy does try to run as much of Taldor as possible, and being otherwise outside of their decision making process would mean they would try to have them brought under or influenced by it.
The order acts as unofficial guards to the Royal family and Grand Prince.
Cut out the Grand Prince part, duder has the Ulfens after all, so they're more known for guarding the rest of the imperial family.
Put in something to emphasize the social primary function of the House so as to not feel infringing on the shtick of the Lion Blades.
Something like, in house overview or such..
"For single or widower Grand Princes, the House serves as a source of elegant companions for event and function that allows them to remain somewhat above otherwise frenzied jockeying for a union with them. They are often found otherwise serving as ladies in waiting to members of the Prince's family, as a source to draw on for such figures without having to allow the influence that would come from picking them out from other factions. This has of course lead some detractors to deride such Grand Princes as have favoured that course of actions as "having the imperial daughters trailed after by whores". The House is otherwise renowned and valued amongst those that appreciate it for providing an elegant and exquisite set of companions and courtesans that fit seamlessly into any event of any scale. While by this point a basically open assumption that any grouping with imperial patronage relates such as it knows to the imperial family, many amongst the royal and senatorial families drawn to their allure simply try keep as much focus as they might to meaningless pleasantries when in their company. This doesn't of course entirely prevent the members of the order from marking out useful bits of information all the same, nor from managing to ferret out the secrets they look for in the first place.
The Order also sees a brisk business in serving to acclimate the often foundering newly raised members of the senatorial or royal castes to their new level of society, often hired to provide crash courses in etiquette and bearing to whole families, or to hang off the arm of a raised up from the common man senator or royal caste noble at enough events until they manage to seem at least somewhat like they fit in. The Grand Prince himself, when looking to seem either magnanimous or to indebt a struggling new noble to his person, will often command the Order to offer such services without cost, on his behalf. They are often otherwise called on to consult in the planning of the various galas of the upper crust by those otherwise without such expertise to draw upon."
