The big picture on Calia is a poor handling of her story on Blizzards part, which stems from them over-fixating on writing Forsaken lore centered around when Sylvanas wanted something. The Forsaken as a whole deserve to be layered, and more complex beyond being used for when when a Horde baddie is needed to throw blight. The Forsaken are a faction of undead, who were once living humans, and their founding and start was in the fall of Lordaeron. Many of these original Forsaken are victims, who became undead through simply being exposed to the wrong grain shipment or loaf of bread.
“For Lordaeron” is still a chant that rings true in the game…and it doesn’t belong just to living human Paladins who play on the Alliance.
Ample Forsaken recall who they were and a time before the Scourging.
Calia has been asked for, for many years by the fan base. Alas, the hyper fixation on Sylvanas as the primary point of Forsaken storytelling means they overlooked many other aspects of the Forsaken. We have a handful of Forsaken who are Lordaeron nobles and more in the game.
Sylvanas was little more than a cruel authoritarian dictator who openly regarded her people as disposable weapons. Need we recall the quote that she regarded them as arrows in her quiver. Speaking as someone who enjoys archery; arrows are disposable weapons. You never fire an arrow you intend to get back.
Calia’s death and rebirth into what she is now is…a failure on Blizzards part. That said, in the Before The Storms book Calia’s compassion for the Forsaken as her people were laid bare, and it was her compassion for the Forsaken that got her murdered by Sylvanas.
Calia presents something interesting for the Forsaken that the Dark Lady could never offer. Calia’s claim to the crown allows for her to be politically weaponized against the Alliance of Stormwind claiming Lordaeron, and wiping the Forsaken off of it. Calia also brings with her political connections.
As for Calia losing her claim to the throne of Lordaeron when she died? This is a world of magic, with the undead having existed in it for thousands of years. After all, Sylvanas was called the Banshee Queen, yet had no rightful claim to any such title.
Tragically, writing for Calia in the game however has shown her to be soft, and devoid of additional depth to make her a more compelling character. I highly suspect stuff was planned and written for her in Shadowlands, and it was dropped…much like many other things when Shadowlands was cut short due to how unpopular it is.
The Forsaken story needs to grow beyond being a fan service for Sylvanas. I and many others welcome Calia as a new chapter. By no means do I think Calia will make the Forsaken weak and soft, I think it marks a new more dangerous era of Forsaken political games that will lean into their better sense of canny, making them effective political tools against the Alliance for the Horde.
That said, I like both Calia and Sylvanas. I am equally big fans of both, and yet see them for being very different characters and leader styles.
