I don't know if a Caesar is more powerful than an emperor giving rise to a question if Boddunan's titles are framed by giving attention to their underlying meanings? Similarly there is feminine form of 'Emperor' which is "Empress' but here female members are accorded 'Emperor' titles which can validly be objected to by them. What do you think?
Let me clear the matter about this.
To be frank, we did not think a person reaching emperor in such a short period when we started this website. And let me clarify that we did not put anything that comes to our mind just like that. So the maximum title we can think of is Emperor and there is no other designation after that. Technically we do not support male or female on forum, sorry about that.
So once we have people start earning more ranks we thought of having more ranks. So what could be the next rank? The only option we have is the list of emperors, alternate meanings or anything that is equal or more important to the greatest rank we have. So we have derived the Caesar rank from there. Btw it is no less than Emperor. Don't ask me about the next rank and let it be secret and be assured that it is at the same or greatest level but never be on the lower lever.
Hope I answered the question.
