2: Atenveldt, Kingdom of - New Badge
OSCAR finds the name registered exactly as it appears in of at some point,
Azure, a demi-sun issuant from base Or and a bordure embattled argent.
The branch-name was registered at some point. This badge will recognize past Kingdom Arts and Sciences Champions.
A demi-sun is "anything less than a full sun". Consider the Shire of Per chevron gules and azure, a demi-sun issuant from the line of division and a laurel wreath Or. The Shire's sun has a "quarter chunk" taken out of it to accommodate the Per chevron... division of the field.
This is clear of Meri En Heh: (Fieldless) On a canton azure issuant from base a demi-sun Or within a bordure argent. This is an augmentation, and although augmentations are checked for conflict before they are registered, once registered, they are not protected against new registrations.
"Augmentations are required to by themselves be free of conflict, as noted in the October 1998 LoAR (James Eldon of York, Kingdom of the Outlands)." [Welfengau, Canton of, 10/99, R-Ealdormere]
