The Heralds of Ultramar is a Loyalist Codex Astartes-compliant Space Marine Chapter likely derived from Ultramarines gene-seed. Its exact Founding date is unknown. Almost nothing else is known about it in Imperial records at present.
The Heralds of Ultramar's appearance is nearly identical to that of their likely progenitors, the Ultramarines. The Chapter's Power Armour is also blue. The Aquila or Imperialis on the chest guard is yellow. The white squad specialty symbol on the right shoulder guard designates operational specialty -- Tactical, Devastator, Assault or Veteran. A black Roman numeral is stenciled in the centre of it, indicating squad number. The colour of the shoulder plate trim indicates company number in accordance with the dictates of the Codex Astartes -- i.e. White (1st Company), Yellow (2nd Company), Red (3rd Company), Green (4th Company), etc.
The Heralds of Ultramar's Chapter badge is a yellow starburst with twelve or five points depending on the source, superimposed over a pair of ebon wings (displayed and elevated) on a field of blue.
