Ah, my apologies for misinterpreting your question; allow me to elaborate here. The Queens are typically referred to as ‘Your Majesty’  when speaking to them, or ‘Her Majesty’ when speaking about them to someone else.

They are also referred to as simply ‘The Queen’ or ‘The Black Queen’ when not in their presence. Other forms of address include ‘my queen’, ‘your royal highness’, ‘our wise and just leader’, ‘glorious monarch of the dark kingdom’ etc. Really, any form of suitably deferential address will do.
