The Dragon Flame was never deemed stronger than the Legendarium. The specified reason for Bloom retaining her Sirenix was because her power source is the source of the magic universe, and she is its keeper.

It is possible that the Dragon Flame could've been born from imagination, like we propose all of the magic universe to be, because you can always birth something stronger than yourself.
