You seem a little confused by our use of symbols and symbolism - and I can understand how arcane our world must look to outsiders. I hope this might help:
White Horse rampant on a red shield: The shield of the county of Kent with a history that dates back to around 500CE when Kent was a separate Kingdom.
Invicta: Latin for "undefeated" -- The Men of Kent resisted the 1066 Norman invasion. The Normans could not beat them and Kent, thus undefeated, was granted considerable autonomy and independence from direct Norman rule - freedoms which lasted until 1925 when the final concession (Gavelkind) was repealed.
HayaSidist: Amharic for twenty six. Amharic was originally the language of Amhara - a province of what is now Ethiopia - and is now the official language of Ethiopia. Amharic is in the same family of languages - Semitic - as Arabic and Hebrew; it is written in Ge'ez script. This is how the number hayasidist would be written.
