FANS of the TV series Game Of Thrones said they were “devastated” as they learned the fate of the Iron Throne in the last ever episode.

However: if you have yet to see the final episode, do not read any further.

The eighth and final series of the fantasy drama came to an end in the UK on Monday night, with a dramatic last instalment that saw Jon Snow (Kit Harington) kill Daenerys Targaryen (Emilia Clarke) by stabbing her through the heart.

Many disappointed viewers said they felt the fan favourite character deserved a better ending.

One posted on Twitter: “I began watching Game of Thrones in 2012 before the second season came out and ever since I’ve always rooted for Daenerys and honestly that season finale broke my heart.”

“This breaks my heart so much #Daenerys did not deserve this at all,” said another.

One person tweeted: “My heart is broken, I demand justice for Daenerys, the only one true character of GOT.”

“Daenerys deserves so much better. I am so devastated,” posted another.

One irked viewer wrote: “You killed Daenerys, all my years of watching was pointless. Bad writing…”

Game Of Thrones, which is based on the books by George RR Martin, started in 2011 and ran for eight series, becoming a global success.

“There will never be a show like @GameOfThrones,” said another viewer.

“I am heartbroken to see it ending but am forever grateful for this masterpiece in television history.

One upset viewer said: “I’ve been bawling my eyes out for years now, but nothing will compare to the feeling of hearing the soundtrack for the very last time.

“And now our watch has ended.”

On his blog, the writer of the books on which Game of Thrones is based, George R R Martin, said that there are still two more volumes to come.

He says: "Winter is coming, I told you, long ago… and so it is.   'The Winds of Winter' is very late, I know, I know, but it will be done.

"I won’t say when, I’ve tried that before, only to burn you all and jinx myself… but I will finish it, and then will come 'A Dream of Spring'

"How will it all end? I hear people asking.   The same ending as the show?  Different?

"Well… yes.  And no.  And yes.   And no.   And yes.   And no.   And yes.

"I am working in a very different medium... never forget. They had six hours for this final season. I expect these last two books of mine will fill 3000 manuscript pages between them before I’m done."
