The Eredar Twins - Lady Sacrolash and Grand Warlock Alythess - are the fourth of the six bosses in Sunwell Plateau, the 25-man raid on the Isle of Quel'Danas. They are fought at the same time, in the Witch's Sanctum, and this page is that one encounter from $98.99.
This is a pre-order. Sunwell Plateau arrives with Phase 4, Fury of the Sunwell, in autumn 2026, and Blizzard has not announced a date. You book at today's price now; the raid team takes your character to the Eredar Twins on the first lockout after Phase 4 goes live on the Anniversary realms.
Why this is the boss that stops guilds. Kalecgos, Brutallus and Felmyst are one target at a time. The Eredar Twins are two at once - Lady Sacrolash is the shadow half, Grand Warlock Alythess is the fire half - so the raid has to split, hold the split, and keep moving through Conflagration without collapsing either side. It is a 25-man assignment and positioning test rather than a gear check, which is why a roster parked at 3/6 can burn reset after reset on it.
The kill is the unlock. M'uru and then Kil'jaeden sit behind the Eredar Twins, so this encounter is the gate on the back half of the tier. Sunwell Plateau runs a 7-day lockout and has no attunement at all, so nothing stands between a level 70 character and the last two bosses except this pull.
Sunwell Radiance is live on this fight: every mob in the tier gets +5% chance to hit and players lose 20% dodge, which is what makes Sunwell tanking different from Black Temple. Blizzard deliberately leaves that aura off M'uru and Kil'jaeden.
Pick the right page. Everything before this is the Kalecgos, Brutallus and Felmyst carry. Everything after is the M'uru kill and then the Kil'jaeden kill. This page is the wall in the middle.
Delivery: piloted by default, self-play if you want to be at the keyboard, or Self-play Remote for 30% more. US realms are the default and runs are scheduled around your own ET or PT reset; EU is on the region switch above.
