No, he did destroy Sekto's dam, and he helped them build a new last legs, but after that he got bored of having nothing to protect them from so he returned to bounty hunting.

And he only bounty hunts at places that nobody has heard of him, like Fowlsburgh, and he wears his old clothes.
And merry Christmas, peoples!
-----
The inside of the grubb temple was bright and cool, with ancient pictures depicting important events in grubb history carved into the walls. The cieling of the temple was a huge translucent dome made out of water-washed limestone. Charlotte stopped to stare up at it before being pulled roughly along by the grubb leader.
"I am Ophelia." The little grubb said as she lead Charlotte down a narrow path below a giant grubb statue. "I will show you how we know."
"How you know my name?" Charlotte asked.
"How we know everything!" Ophelia beamed, glowing with pride. She let go of Charlotte's hand and ran over to a stack of torches to her left. She grabbed one, lit it with a match, and continued leading her down the winding path. Eventually the light from the bright temple behind them faded away in the dark, and all that was left was torchlight.
"Wait! Wait for me!" A voice screamed from behind them. Mola, who was no longer dazed, caught up with them, panting heavily. "Why didn't you wait?" He whined, dragging his feet with each step.
"Because you shouldin't be following us," Ophelia hissed.
"Psh," Mola sighed with a flick of his head, "you don't mean that."
"I do, now be quiet or the elders'll be pissed!"
"Who are the elders?" Charlotte asked.
"They're our expert seers." Ophelia explained. "They look in the water and tell us our future."
"They're old geezers, they can barely
see anything."
"Mola!" Ophelia snapped, her voice echoing through the tight passage. "Show some respect for our elders! Now, granted, they're old..."
"...very, very old..."
"Just let it go." She sighed, defeated.
Ophelia dipped the torch into the wet ground, extinguishing the light. Charlotte was about to ask why she had done that when suddently she was aware of a dim blue glow up ahead. She stumbled towards it, walking with a haphazardly akwardness. The glow grew more and more defined, and shimmered like sunlight reflected off of water.
"Not long now," Ophelia whispered, "...and by the way, once we get there, don't talk. They don't like it."
"Once we get where?" Charlotte questioned. Ophelia shushed her immediately.
The blue light was glowing from a gap at the end of the tunnel. Ophelia lead them through it, and the three soon found themselves in a small room where five old grubbs sat around a crystal pool, murmuring to themselves. The immense silence was almost painful, and it left an annoying ringing sound in Charlotte's ears.
"This is it?" Charlotte whispered, breaking the silence. Ophelia stepped roughly on her foot, silencing her.
One of the elder grubbs lifted his head and looked Charlotte over with his fading vision. He prodded the grubb next to him with a long, thin finger.
"Reed, look," he said, pointing to Charlotte.
"Wha? Where?" The grubb looked around blindly. The other elder shook his head.
"Old coot! Right there!" He hissed, pointing at her again.
"Charlotte," Ophelia said, sweeping her hand out in front of her, "Meet our elders- Reed, Minnow, Brook, Beetle, and Cod. They predicted you would come."
"Hi." She said, waving weakly. She still didn't understand why she had been lead here.
"Sit down." The elder known as Beetle said. "We have much to discuss."
"About the past," said Minnow,
"...the present..." said Brook,
"...and the future!" said Cod.
"About everything." Reed finished, folding his hands neatly. Charlotte blinked slowly and sat down. Mola and Ophelia followed.
"You!" Brook said, suddently pointing at Mola. "Rouge! Get out of here! You break everything you touch! Waste your energy outside, get some work done!"
"Oh come on!" Mola protested, throwing his hands in the air. "You never let me stay--"
"The last time we did," Cod growled, "you almost broke my neck!"
"I tripped!" Mola yelled.
"Mola," Ophelia said, "get out."
"Fine! I'll go, if it'll make you old goats happy," Mola groaned, laborously getting to his feet and dragging himself out the door. Minnow chuckled.
"Idiot. I predict he'll get himself beaten up soon, that'll teach him."
"Me too." Reed agreed.
"Anyhow," said Brook, clapping her hands, "back to buisness."
"Tell me," Charlotte said, "how did you know I was coming? And how did you know my name?"
"Shush, darling." Brook said with a wafting notion of her hand. "Everything will soon become clear, just wait."
The room became deathly silent. The five grubb elders sat motionless, their eyes closed and their minds deep in thought. Their breathing was shallow, and Charlotte wondered if they had all keeled over and died simutaniously.
"Just wait," Ophelia whispered, also closing her eyes, as though trying to predict something herself. They sat in this position for more than half an hour. The entire time Charlotte sat and twittled her fingers, her patience dwindeling. Finally somebody spoke while Charlotte was in mid-yawn.
"Interesting!" Cod said, bobbing up and down with exitement. "Very interesting! We will need to prusue this further; but for now I think I would like some fish."
"Wait!" Charlotte said, standing up. "Aren't you going to tell me why you've called me here?"
"Oh yes, that." Beetle said, scratching his chin. "We believe you're meant to rescue the remaining handful of steef from extinction. Pretty wild, eh?"
"Pretty wild?" Charlotte yelped, her voice shrill. "
Pretty wild? Why didn't anybody tell me this? I don't want to save anybody, I have a hard enough time saving myself!"
"Calm down!" Ophelia yelled, sounding just as suprised. "I just found out, too! We all just found this out! Its not worth getting all worked up about."
"What?! Is this a
joke?" she demanded, waving her arms in the air. She began walking in a tight circle, whispering 'I can't do this, this is insane, what the hell' repeatively.
"Come on, its not that bad." Reed said.
"Not bad at all," Minnow agreed. "We don't even know if our prediction was real or not. No need to get your fur all ruffled up."
"Right," Brook sighed, standing up. "I think i'll get some lunch."
"Me too."
"Yeah, I could do with some fish."
"Uh-huh."
The five grubb seers filed out of the room, muttering to eachother about their predictions. Charlotte lay face-down on the stone ground, rubbing her tempels.
"If there's not an explanation to why my life has to be so confusing up to this point, I think i'll shoot myself." She said. Ophelia laughed.
"Thats the spirit, Charlotte! Nothing like a joke to relieve some stress, eh? Eh?"
"I wasn't joking," Charlotte growled.
"Oh." Ophelia sighed. "Uh, okay... i'll just leave you to... whatever it is you're doing." She said, leaving the room.
Charlotte groaned and sat up, wishing somebody would knock her out with a heavy brick.
