It's Not Mine

Klaus and Reynolds stayed in the same location as they waited patiently. As time went on, more people were attracted to the place, but no one had made a move yet, no one wanted to be taken advantage of. 

In the crowd, there were already four Elemental Venerables, but the Sage Plane Elementalists had the higher number, as long as they worked together, they would be able to fight against these Elemental Venerables. 

The Elemental Venerables are aware of this, hence they didn't move rashly. They were all in the Early stages of the Elemental Venerable Plane, so they didn't have an overwhelming strength over their opponents. Against one person or two, they could win, but with the numbers of Sage Plane Elementalists present, it would be difficult for them.
