The Tree Father's choice

*Sshhhh~*

With a wave of his hand, the restriction on the souls of the three Tree Fathers was eased. Now they were able to speak again and move slightly, but they did not begin to speak right away, Rather, each of them began to look at the other two as if waiting for someone else to begin speaking, and then finally their eyes turned at the same time towards the deer girl...

The spirit of the planet abandoned them and is literally seducing an invader coming from another world to refine her for himself. They spent hundreds of thousands of years sensing her presence and then trying to refine her and kill what they killed for her, but in a moment she threw them aside as if they were trash... How is this different from your lover cheating on you? If these were their real bodies when they were still Treant creatures, one of them might have started crying by now.
