Rex Perpetuus- Eternal King (I don't know how to say "appointed by God" in latin, so I used that.
Magister Mundi sum- I Am master of the Universe!
Imperator Imperatorius Britanniae- Imperial Britannic Emperor
Dylan Pavonis Rex- King Dylan Peacock (Pavonis is the Gentitive form of Pavo), perhaps it also means Dylan, the peacock king?
