"Kobolds, retreat at once, after I've flown far enough away," the dragoness said, and flew off like a rocket.
The kobolds ... realizing they were alone, with the skeletons as useless as statues, ran, actually dropping their cheap gear so they could run away faster.
"First, thank you," said the hero to the original dryad.
"You can thank me by turning into a dryad," the original dryad said. The new one nodding eagerly.
"That is utterly impossible," said Adrian.
"Well, maybe me and my sister will just add these humans to our glen instead," the original dryad said with a smile. The villagers, having grown used to being on the receiving end of fae, were-beasts, demons, dragons, and undead, only cringed in fear.
"If you do. I will stop you, by whatever force possible. Both of you."
"Oh I'm so scared," she stuck out her tongue. "You 'kill' me, and I'll just reform at my tree sucker!"
"Except you won't." The hero said simply. "Didn't you notice? You've long left the forest, you're well outside of the range you should be able to travel beyond your forest safely."
The dryad was about to tell him how stupid he was... but realized he was right!
"And in case you didn't notice. You just transformed a DEMON into one of your kind.
"There is no way in the Nine Hells you should have been able to do that, normally. It should have been impossible. Demons as they appear on our plane of existence are just shadows projected onto our reality from their native state of existence. Yet your magic was strong enough to somehow to either possess a demon's projection, which at point Doomvak now suffers humiliation worse than death for being 'slain' on the mortal plain, or you somehow pulled a demon's true self onto our reality and bound it to its project. That isn't the kinda power a dryad normally has."
The dryad shuddered. "Then... then how..."
"I'm a Chosen One. That means I share that power with companions... you traveled beyond your home to be with me, and you followed me into danger to remain at my side. That makes you a companion... it also means you're bound to me. If you try to leave me, it'll be as fatal as if you tried to leave your forest. It also means that if you did transform, which you can't, it's not matter of power, you're so far away from your forest that you, I, and your new sister would all die instant."
The words the dryad blurted out were untranslatable. She tried to turn a random human child she saw clutching his mother into a dryad sapling in an act of defiance... only to find transforming Doomvak had drained her mana reserves completely (her countless wasted attempts on transforming the hero hadn't helped).
"Let's start again. My name is Adrian, Chosen One, the Unflippable Hero, destined to topple the Triad Empire. It's a pleasure to meet you, what is your name?"
"Pst. What use do I have for a name? Do all the trees in the forest need names? THey're part of a whole. We need no such things."
"Well, it'll become impractical to call you 'Dryads' over and over. What about Dina?"
"NO!" The dryad raised her hands in horror. "What... What you done?! A name?! Agh! It's stuck in my mind! My name is Dina! I can't go back to my sisters now! I'm a freak!" Dina waved her hands upwards hysterically.
"Uh, you can call me Lilly Mr. Hero," said the second Dryad.
"AGH! You just infected my little sister too!" Dina accused. "Neither of us can go back to the forest now! We're abominations!"
"I think Dina is a nice name."
"Shut it Lilly!"
"Sorry big sister."
"Uh, yeah, oops, I... I apologize," said the hero awkwardly. "Being able to name your companions if they don't have names was a power of the Chosen One too... doesn't get used much."
"So now we're stuck with you! And you won't even let me form a new glen out of these stupid axe-swingers! I'm nothing!"
"... The Triad Empire would eventually turn your forest into a hunter ground, corrupted to their will, or simply clear cut it. If you help me topple their rule, then I'm certain your sister will become you back with open arms, named or otherwise."
"That sounds really cool! We're gonna save the forest Dina!" Lilly cheered.
"... Doesn't look like I have a choice," Dina sighed. "... Normally at times like this I'd find satyr hanging out with his frat boys to relieve stress. Now I don't even have that."
"Sorry, asexual."
"That explains so much," the dryad groaned.
"Now if you'll excuse me, I'll join the villagers in putting the fires out."
"Huh?"
"If you weren't busy feeling sorry for yourself, you'd have noticed the villages with the monsters gone had already started trying to save their home from being completely ash. I should have gone straight to helping them, but I didn't want to risk you going on a rampage with their backs turned."
The hero made gestures with his hands, causing balls of water to form out of the air, followed by earth, combining into mud to help smoother out the flames of the near house.
"You know magic too?! What the Unseelie Court ARE you?!" Dina demanded.
"HE'S SO COOL!" Lily shouted.
"A Chosen One, remember? Drafted by the gods to protect the innocents from tyrants and mad men. I'm not an archmage or something like that. There are just too many monsters immune to physical damage to NOT know magic to defend myself with. Now help!"
"I'm made of wood, what makes you think-"
"You're a dryad! You protect the forest! That includes dealing with forest fires! Now help!"
"... Dangit, I was hoping you didn't know that! Helping humans in a way that doesn't turn them into my sisters makes me sick."
"We're gonna help lots of people!" Lily vowed.
"Good sir, if this is a dream, I sincerely hope I never wake up," said an old man once the last of the flames were out. "You saved me, my family, my friends, my neighbors, all of us from becoming demon cattle or worse. May the gods shower you with love."
"You're all fools!" Said a young man. "Now that we've defied them, the Emperors will send an entire army to destroy us all as an example!"
"Or hearing a demon was turned into a dryad is going to spook them so badly that they'll cover up this even happening, forget your town even exists, and not come within a hundred miles of here," said the hero.
"Our town welcomes you to rest and ready yourselves," the old man looked around at the burnt houses. "Such as it remains. We have a lot of reconstruction ahead of us."
"Not as much you think, Lilly, you can help them can't you?"
"You got it Mr. Hero!" Lilly saluted. Lilly's entire body glowed, green transparent wings briefly bloomed from her back. Plants sprouted from the ground, hardening into wood, consuming and replacing the burned and broken beams of the houses, doing months of reconstruction in minutes... Lilly fell over dizzy.
"... I get it," Dina said rolling her eyes but also kneeling next to help her sister. "She was created from a demon, a fallen angel, which isn't supposed to be possible, so the amount of magic she can do off the charts. Which you already guessed."
The hero nodded.
"Maybe dryads aren't all bad," said one bearded man, missing an arm.
Lilly would have grown him a wooden prosthetic arm on the spot, but she was ten minutes old and had just given the town a giant head start on their repairs, give her a break.
