I Have a Theory regarding the Spirit champions

So far riot has released up to 2 spirit based champions them being Bard and the other being Kindred. Both represent a certain aspect of the spirit world Bard represents the protection of life and of the spirit world he is a protector of all, While Kindred is in basis the spirit of death. Now riot will most possibly release 3 more champions that are spirit based and theorize what they might be . For one they can make a spirit that represents the other of aspect of death that being the bringing of life. After that they might make 2 champions on that is chaotic good and chaotic evil. They will represent the over obsession or protection of what is known as they cycle of life and death. I may just be wrong but hey its to theorize isnt it haha
