Spoiler alert: This story contains significant details from Sunday's series finale of HBO's "Game of Thrones."

Emilia Clarke's watch has ended.

Clarke, 32, took to Instagram to bid an emotional farewell to "Game of Thrones" and her fiery character Daenerys Targaryen ahead of Sunday's 80-minute series finale.

"Finding the words to write this post has left me overwhelmed with how much I want to say but how small words feel in comparison to what this show and Dany have meant to me," she captioned a group photo of the costumed cast, including Kit Harington (Jon Snow), Sophie Turner (Sansa Stark) and Maisie Williams (Arya Stark).

Clarke, who has played the Mother of Dragons on the hit HBO show since 2011, noted that her portrayal of Daenerys has "taken up the whole of my adult life."

"This woman has taken up the whole of my heart," she wrote. "I’ve sweated in the blaze of dragon fire, shed many tears at those who left our family early, and wrung my brain dry trying to do Khaleesi and the masterful words, actions (and names) I was given, justice."

Clarke's post included a casual picture of the cast hanging with showrunners David Benioff and D.B. Weiss, as well as a shot of her signature "platinum wig of dreams."

"Game of Thrones has shaped me as a woman, as an actor and as a human being," she wrote. "I just wish my darling dad was here now to see how far we’ve flown."

The British actress called the show's fans "magical," thanking millions of viewers for their "steady gaze at what we’ve made and what I’ve done with a character that was already in the hearts of many."

Clarke concluded: "Without you there is no us."

She was not the only cast member to reflect on time on the HBO series.

Sophie Turner posted her own group shot to Instagram with a message to her character, Sansa Stark: "Sansa, Thank you for teaching me resilience, bravery and what true strength really is. Thank you teaching me to be kind and patient and to lead with love. I grew up with you. I fell in love with you at 13 and now 10 years on.. at 23 I leave you behind, but I will never leave behind what you’ve taught me."

Turner shared her satisfaction of Sansa's fate with Entertainment Weekly, despite not getting a place on the Iron Throne.

“I wasn’t bummed at all," Turner shared with the outlet. "Because ever since the end of Season 1, Sansa has not been about the capital or being queen. She doesn’t believe she could rule and doesn’t want to. She knows her place is in the North and she can rule the people of the North and rule Winterfell. … But she has no desire to be ruler of all of the Seven Kingdoms.”

Isaac Hempstead Wright, who played Bran Stark, shared with the Hollywood Reporter that he was "thrilled" about his character becoming king.

"At the beginning of the show, Bran is a disabled 10-year-old with slim chances of surviving in this harsh universe," Hempstead Wright wrote in a guest column for the outlet. "I find it an extraordinary character arc to see him go from a vulnerable character totally dependent on others to the one person who holds all the keys to understanding the world."

He continued: "Bran becoming king is a victory for the still and considered people of this world, who too often get side-lined by the commotion of those who are louder and more reactionary."

Hempstead Wright said the realization that the series was ending hit him while filming the final Dragonpit scene where his character is selected king.

"This was to be the death of my character; it would be the last time I would ever breathe life into him, the last time I would sit in my costume on a 'Game of Thrones' set and think about what it feels like to be Bran," he wrote. "That was something I had done as a regular fixture of my life since the age of 10, and so it felt very sad to be saying farewell."

Before the finale aired, Brienne of Tarth actress Gwendoline Christie posted a photo of herself and Kit Harington (holding a definitely not-prop-team-approved smartphone) with the caption: "BEING TOLD THE ENDING TO @gameofthrones"

Jacob Anderson, who plays Grey Worm, compared the show to "the craziest school trip ever," adding, "a 6 year Adventure Weekend."

"Grey Worm. You went from a robot to a real boy. I’m proud of you. I’ll miss you bud," Anderson wrote to his character. "Thank you to everybody that cared about him and rooted for him. He was really scared at first, but you made him feel loved. He appreciates it. I asked him."

John Bradley West, who portrays Samwell Tarly, shared a picture of a souvenir from nearly a decade ago.

"So tonight we have our very last episode," he wrote. "It’s the final step of a long and wonderful journey. A journey that, for me, started at 10am on Monday 19th of July 2010. I know this because recently I found my rehearsal and prep schedule for season 1, week 1."

The schedule included West's first rehearsal with Harington and his first costume fitting.

"I’m glad I kept this. I met so many people that week who have come to mean so much to me," he wrote. "Back then we couldn’t have known the journey we’d go on together. I wouldn’t swap that experience, or those people, for the world. Enjoy the episode and thanks for everything."
