The only real effort to work with the Vasudans beyond a brief flirtation with them, to really give you an immersive viewpoint, was Shrouding The Light.
For a never-done campaign I worked on, much was made about how the Vasudans ascribe great importance to names. To share something's name is to share its legacy and deeds: a great deal of emphasis is placed on the spiritual and traditional link when something shares the name of something else from the past and a name (whether personal, or even collective like a unit's) can be removed from the larger society by having accrued too much taint of failure, evil, treason, or murder. "Collective" names, such as for a group, are usually purely descriptive. A Vasudan squadron or battlegroup is described purely by its type and number. Nicknames like those applied to a Terran unit are not informal, they are marks of distinction granted by decree of the Emperor and describe a quality or concept the unit is considered to embody.
The examples at the time were the 223rd Medium Fighter Squadron, granted the name "Steadfast" for a single marathon forty-six hour sortie during the Siege of Vasuda Prime where they held the Vasuda-Antares node open for those escaping. And the 33rd Heavy Fighter Squadron, granted the name "Vengeance" after the settling the longest and most bloody military grudge match since Vasudans attained spaceflight: a battle against the PVD Prophecy and its works that began during the Great War before the Siege of Vasuda Prime and ended two years after the Second Shivan Incursion.
