Actually I think the Water Stars give us a good idea as to the relationship. As the elemental opposite it and the Dragon Flame cannot exist in the same place for long (after season 3 the winx probably returned them) without driving the universe into chaos. Most likely the same is true for the Phoenix energies as being the direct opposite of the Dragon Flame. It's probably natural that the Winx would destroy Darkar to keep the Dimensional balance intact.

Aso fun fact Domino's name is drprived from the word Dominous which is used as aa name for/meaning in latin of God, which the Great Dragon serves as the Stand-in for in the Winx Club Universe. Also the name Marion is depreved from the name Mary, and Bloom being so intwinded to the point her magic and life is the Dragon Flame... you can probably get what I mean.
