To be honest, Dirga wasn't that curious about Mekar. He knew the boundaries between humans and Wrena, and if a human refused to meet him, then he would not force his way in and just leave.
Mekar's reaction to him was normal, and Dirga was clearly aware of it. He had often seen various humans run away at the sight of him without even having the chance to make a sound first.
It's normal. Dirga never chased after any human who ran away when he saw him, long ago, when he was still very curious about human life. That's why he likes to approach the clergy, because they are not afraid of wrena, and they are open to all kinds of information.
He knew in general terms why Edwin had forbidden him from approaching Mekar. He wouldn't ask more; maybe he could find out more if he won Edwin's trust, even though Dirga was sure it would be very difficult to get.
But at least he will try to get it.
