Things might even be looking properly interesting now, if that guy keeps his promise.
Tenno will just have to act as polite and friendly as he can, then. He greets them both, in person, at the edge of the forest, and introduces himself, and offers fruit.

"Phila, I will not hurt. Fight is ugly." And he starts asking vocabulary questions.
This is not maximally productive. He points at the 'guard.' "You! Go away!" He makes a significantly less evil-looking sort of imitating-a-clearing thing at the edge of his 'evil forest,' including convenient places for a human to sit. He sort of- kneels down, sitting not being practical for a quadruped. Nonthreatening as can be, given that he's still obviously very magic and she's used to violence from magic-having people.
"No. I said, go. Away." A thorn-encrusted tree is reaching out for the 'guard,' now, but refrains from actually striking.
The tree goes back to where it was. He curses a bit in his own language, then calms down enough to ask, "Why so much fight? Is-" Irritating, wasteful, ugly, so painfully human- "Sad."
Headshake. "I have my trees. I fight for- Defend? Is word?"
He shrugs and makes a frustrated gesture. "Fight is ugly. I fight to stop fight, or stop fire, or stop kill."
"I think that is almost right. What is word for, make things look good?"
"Then I fight to protect improve." Nod, nod, clearly there has been no misunderstanding here.
