MAE SAI - A football team made up mostly of poor teenagers entered a cave in northern Thailand a year ago on a day trip, accompanied by their coach.

They emerged 18 days later to global acclaim, courted by film producers, authors and talk show hosts eager to tell the remarkable story of a daring operation that rescued them from the flooded cave.

Most of the 12 "Wild Boars", as the team was known, still live in the poor northern town of Mae Sai, once a sleepy place but now inundated with selfie-snapping tourists.

They still play football -- their coach who led them down the Tham Luang cave complex continues to run training -- and they share the same basic homes with their families.

But life for the team has changed.

They have signed a film deal with Netflix, travelled the world, and had their story told in books, documentaries and a number of films.

But their new-found fame has also forced silence on them, as the boys and their families can no longer talk freely about their ordeal -- the result of contracts that ban them from speaking to the press.

- Stateless no more -

The boys were on a day trip to the cave complex on June 23, 2018, when up-country rains flooded the complex.

They were feared dead until two British cave divers negotiated a series of narrow waterways and corridors and found them on July 2, trapped in a damp chamber, four kilometres (2.5 miles) from the entrance.

It was then that Adul Sam-on, aged 14 at the time, became one of the stars of the drama.

He went into the cave complex as a stateless person -- like several others in the group, including the coach Ekkapol Chantawong, denied citizenship in Thailand.

But the world heard his "thank you" spoken in English to the British divers who found the group, cold but alive, nine days after they went missing.

Born in Myanmar's Wa State and raised in Thailand, Adul had no birth certificate.

After their dramatic rescue, Adul, his coach and two other teammates were granted citizenship and passports for the first time, allowing them to travel to destinations from Los Angeles to Manchester.

With the anniversary of the start of the saga this Sunday, those close to the Wild Boars say fame has not changed them.

"He's an ordinary person just like before," Adul's friend Aman Sommol told AFP from his school.

"He's a role model for the younger kids at school," Aman added.

Adul and several other Wild Boars now play for the Ekkapol Academy, a new club founded by Coach Ek, as he is known.

As he runs drills Ek smiles at the visiting media, but bound by Netflix's contract he cannot talk about the cave drama.

Rumours have swirled about payments to the boys -- US media has pinned the number at $100,000 for each.

- Lucky number 13 -

Fame has also come to some of the divers who helped rescue the boys.

After weighing several options, the boys and the coach were eventually given sedatives and brought out wearing wetsuits and full-face breathing apparatus in a series of relays.

Extracting everyone took three days because crews had to replace air tanks and other supplies, requiring up to twenty hours between each run.

Many of the rescuers were Thai Navy SEALs, some were experts running tourist dive operations, while others were lifelong cave hobbyists who flew in from Britain and Australia to assist.

All found themselves at the heart of a drama.

Among the rescuers was Saman Gunan, the only fatality during the near three-week saga.

Today a statue of the Navy SEAL, who ran out of oxygen in a twisting, flooded passage, stands near the cave's entrance.

Other rescuers like Vernon Unsworth were pushed into the media spotlight against their will.

Speaking to the BBC, Unsworth played down his central role in helping the trapped thirteen to safety.

"None of us are heroes. We just did a job we were asked to do," he said. "Thirteen is not an unlucky number anymore."
