So a question about character lore and possible changes

So I wanted to make this thread to clarify when and where we will have changes to lore Hopefully a dev sees this
Here goes. Just wondering what exactly it takes on the technical side to go about changing lore on a specific character
Will it be something that is done on server side or is it going to be something that’s added through an update

Also any idea on how many characters are getting lore changes assuming there are any
