New Sylvanas Spell Added in 10.1.7 - The Dark Lady Returns for Undead Heritage Armor Questline?

In the recent Patch 10.1.7 PTR build, we datamined a new spell simply called Sylvanas. While information is limited, we suspect we may be seeing the Dark Lady return in the new Forsaken Heritage Armor Questline. Forsaken Heritage Armor Preview

The Sylvanas spell is very little to go off of, but follows similar spells related to a lot of the triggers for Sylvanas found throughout Shadowlands. While this might just be an oddly named spell that happened to be slipped into the recent patch for other means, the Forsaken are receiving their Heritage Armor Questline in Patch 10.1.7 so the line up just seems more than coincidental. Despite the dark path Sylvanas walked alongside the Jailer in recent expansions, much of the Forsaken Legacy was built by Sylvanas as she fought for a proper kingdom and place for the undead of Lordaeron. She strayed from that initial vision and committed unspeakable atrocities in her alliance with the Jailer. While many factions saw some resolution with Sylvanas in the Shadowlands epilogue as she accepted her actions, her interactions with the Forsaken were limited and left not fully explored as she left to perform her penance in the Maw at the end of Shadowlands. So why or how would Sylvanas make a return? We know that a schism still exists within the Forsaken between those that support the new Desolate Council and Sylvanas Loyalists. This divide within the Undead could ultimately destroy everything the Forsaken are looking to rebuild. Despite the exceptional work the Desolate Council is doing for all the Forsaken, Sylvanas may be the only one who can mend this festering wound and unite her people in a common future. Can she share the hope she felt in the Shadowlands epilogue
