Saya mau tau Lencana dari Gray's Inn. Jelaskan dalam bahasa melayu

The Badge of Gray's Inn is, in blazon, "Azure an Indian Griffin, proper segreant" or "sable a griffin segreant or" — a gold griffin with a black background. The original badge was the Coat of Arms of the de Grey family slightly altered, but these were changed at some point between 1594 and 1606, with the new arms probably adapted from those of Richard Aungier. This was for two reasons; firstly, he was a particularly important and prestigious member of the Inn, and secondly because the arms looked more impressive on occasions such as masques and revels. The motto around the Badge is Integra Lex Aequi Custos Rectique Magistra Non Habet Affectus Sed Causas Gubernat'', or "impartial justice, guardian of equity, mistress of the law, without fear or favour rules men's causes aright".
