When two forces combine, a new force is born. Either the first one will take over the other or the second one will weaken the first. Sometimes, as it may happen, both can combine proportionately and the resultant force can be somewhat mystical, somewhat magical. And if not, each of them will destroy the other, leaving behind a huge cloud of ashes and smoke. It could even leave no residue, just perish whatever comes in the way;
And erase every mark of their existence.
