Perhaps a story involving a Poro that makes friends with both Braum and Lissandra, despite the clear differences and ideas that they have. i.e. Braum defending the current Poros and Lissandra creating new homes out of the old ones with her ice magic. Both would be in conflict because Braum would see it as an attack and Lissandra would see it as getting the the way, but the poro that is friends with both of them just wants to live peacefully with them and his poro friends. Eventually the poro would get them both to see what they are doing and come to an agreement for the betterment of the poros that they were trying to help in the first place.
