My guild is made up of long-time gamers, including folks who've been roleplaying for dang near two decades. And even though we like to style ourselves "hardcore raiders," we all have to admit that we have those characterization inclinations from time to time. We like our immersion. We like our stories. So when we came across Lady Deathwhisper, we had to make a story up for ourselves.
As the story goes, we met and defeated Kel'Thuzad back in Naxxramas. But, Arthas wasn't quite finished with his trusted lieutenant yet, and raised him (again) from the dead. But something went horribly, horribly wrong. Lord Kel'Thuzad returned from the grave as Lady Deathwhisper! Naxxramas was only a setback, but it was one heck of a setback!
While this little story of ours has no real basis in real game lore, the comparison between the two characters is absolutely appropriate. Both boss fights involve heavy magic damage, adds that spring from the walls to defend the boss, and more than a little coordination. I actually think Leady Deathwhisper is the most difficult fight of the first wing of Icecrown Citadel, which makes her a decent comparison to Kel'Thuzad.
Let's take a look behind the jump and start breaking down the fight.
