The Great Sun, symbolizing solar radiance and solar heat, as well as symbolizing the House's connection to Shävwa. it's the primary symbol of House Ard an Greine. It appears on heraldry and house banners of the personal armed forces guarding the estates of House Ard na Greine. The Great Sun also comes in a few other varieties. One of these varieties is that of the Great Sun but with eyes, nose and mouth weaved into the golden circular body of the sun, forming a face. This variant is of the earlier variant of the sigil, but can still be found within the halls of the many estates of the House Ard an Greine.

The last variant of the Great Sun Sigil of House Ard an Greine, is very similar to the appearance of the official sigil. The only thing that was to set them apart, is the circular body of the Great Sun itself. While the official and representative sigil of the House was a filled out circle of golden yellow, the other variant was only a thick circle with black in the centre.

The Secondary sigil version of the primary appearance was most used for their soldier's armour and banners, unlike the house banners one would find at House Ard an Greine's many properties. The primary sigil was also used at Summer Courts and any other formal situations for the House members.
