When word of British actor Alan Rickman's death flew in on Thursday, Muggles around the world collectively took to social media to raise their wands to his character -- the beloved Professor Severus Snape.
While Rickman had countless notable and extraordinary roles on screen and stage, many remember him as Professor Snape in the "Harry Potter" films.
Fans of the series loved Rickman for the way he brought to life the character they first fell in love with on the pages of J.K. Rowling's books. Doting his notorious dark black hair, cloak and soulful eyes, he was a complex antagonist fans couldn't help but love.
And that was more apparent than ever when fans took to social media to remember Harry Potter's professor, and the man who would always love Lily Potter -- Severus Snape.
From videos, to artwork to quotes, Potterworld collectively mourned the loss of Rickman, and subsequently his character.
And it seems a memorial even began growing at Kings Cross Station in London at Harry Potter's "Platform 9 and 3/4."
Fans were not the only ones to share tributes, former "Harry Potter" cast members also took to social media to pay tribute to Rickman. Daniel Radcliffe, who played Harry Potter, penned a note about Rickman on GooglePlus. He said Rickman continued to support him even after Harry Potter.
"People create perceptions of actors based on the parts they played so it might surprise some people to learn that contrary to some of the sterner(or downright scary) characters he played, Alan was extremely kind, generous, self-deprecating and funny. And certain things obviously became even funnier when delivered in his unmistakable double-bass," Radcliffe wrote.
Emma Watson, who played Hermione Granger, also expressed her grief on Facebook and Twitter.
Tributes from fellow "Harry Potter" cast-mates seemed to be endless.
And J.K. Rowling, the author who brought Snape into the world, also honored a "magnificent actor & a wonderful man," on social media.
So when the time comes we all must die.
But fans of "Harry Potter" solemnly swear to remember their dear professor, "Always."
