uh no? Its just visual effects. Merlin is a candidate for a Grand title (that doesn't mean that he is now the Grand Caster just because Solomon's gone. It is yet to be officially annouced if he did ascend to that title) , while King Hassan shred his Grand title to grant Tiamat the concept of death during babylonia singularity.
TL;DR: just an eye candy effects, nothing special to it
