Self or Legacy
Ryu's instinct was to kill these two. He might have grown quite a bit in recent years, but it hadn't made him any less murderous.
The reason he didn't was because he knew that short-term satisfaction would only ruin everything else.
Right now, he still hadn't managed to find Mae. Of course, that wasn't because he couldn't sense her, but because he had yet to find the time to do much of anything. He was being watched like a hawk from all sides, and the last thing he needed was to offend a faction with a Dao God to the point they felt justified in hunting him down.
In addition to this, he had left Selheira behind at her insistence in the army as well. She wanted to grow on her own, and her pride as a Dragon wouldn't allow anything less, so he had been forced to oblige. Though, he had also left Empana as a form of protection for her.
