For Champions with obsolete/incorrect lore, can you put the following (or something similar)?
#"This Champion's backstory is out-of-date, and will be retold at a later time."
For instance, Soraka's backstory will no longer work because of Warwick getting a complete rewrite. His whole "wants Soraka's heart" schtick will be gone, and thus keeping Soraka's old story around will just confuse people.
I honestly feel like it'd be a good idea for Champions who don't have an up-to-date story to have their Universe entries be scrubbed and fitted with generic placeholders rather than leaving their old stories that will surely confuse the hell out of readers and cause them to ask wrong questions (i.e. "Where's the League of Legends located?").
It'd also be the safest approach, as putting in a brief summary of what the Champion is about long before a complete story is written is a recipe for disaster. These stories are works-in-progress, so if said story changes, people will bitch about how it doesn't match the summary. Having said summary replaced by a "No lore yet. Be patient." notice would piss less people off.
