Úlfhéðnar entered a treaty in 748 CE, known as the Skjǫldrinn Covenant of 748, unifying all three subspecies of Úlfhéðnar, consequently also formally forming an alliance with Jǫtnar, and bringing all Berserkir serving with Úlfhéðnar under the protection of the order.
Skjǫldrinn is the original military order. It has been alternatively under control of Úlfhéðnar from three Norwegian royal blood lines, namely **Sverreættin (**Sverreætten in modern Norwegian, House of Sverre in English), Harðráðiættin (Hardrådeætta in Norwegian, Hardrada Dynasty in English), and Hárfagriættin (Hårfagreætta in modern Norwegian, and Fairhair Dynasty in English), as well as one Danish royal blood line, namely Knýtlinga (House of Cnut in English).
It is currently under the control of the heir of Sverreætten, Áskunnr hinn gullúlfr Bjǫrnsson (also unofficially known as Hákon VI), and soon his son(s), with this royal house more recently being referred to as Áskunnrættin (House of Áskunnr).
Next in line is Harðráðiættin, Knýtlinga, and Hárfagriættin. All by consensus (secured through a lot of fighting and subsequent treaty).
The Blendingr and Úlfheðinn who controls Skjǫldrinn also controls all direct and indirect aspects of the order, and traditionally associates his blood line war banner in all aspects of the organization’s operations. Skjǫldrinn being under the control of Áskunnr hinn gullúlfr Bjǫrnsson currently (Áskunnrættin, formerly Sverreættin), his blood line war banner is therefore prominent throughout the organization. Including Norðsherstjórn (NHS) or Northern Troops Command currently.
Norðsherstjórn (NHS) is in command of Jómsvíkingar (JK), which is the contracting operation in modern times as it was historically, also acting as main troops for the protection of the homeland as required. Væringjar (VG), the Varangian Guard and the Tier One group within Jómsvíkingar. Finally, Ásjárstjórn (AS), or Protection Command, also acting as security and police force.
There is also Áskunnr & Brœðr, the more mainstream outfitting operations, not listed as kept separately for many reasons. Traditionally, trading and commercial operations not related to martial stuff have used a blue banner. This is still the case.
