Warriors captain Matt Kvesic was the first signing made in the squad rebuild, having made more than 160 appearances in two previous spells with the club.
“What a year it’s been, it’s not even been a year since we got together, so I’m a little bit lost for words and emotional,” he told BBC Radio Hereford and Worcester.
“It’s just different – the whole story about the uniqueness of what’s happened here, the way we’ve come back together.
“I don’t think another team has done this, come back into professional rugby and won the league the way we have.”
Warriors will play second-tier rugby again next season after promotion and relegation was scrapped earlier this year.
But chairman Christopher Holland said there was “a belief in the direction we are travelling” and “a determination to continue building a future”.
“The players and coaching staff deserve enormous credit for what they have achieved this season,” he told the club website., external
“This time last year, there was no squad, no coaches, no medical team, no analysts – just a vision and a belief.
“The team we built have consistently demonstrated the standards, resilience and ambition necessary to compete at the top level of this league.”
