Defeat Zakkaru and collect the Sealed Sang'Thraze.
The blood speaks. I can feel its flow through the sand...drenched in death, a desert of suffering...
<Mazoga's eyes roll back in his head.>
There! The blood flows to the south, in a valley of bones. Zakkaru! Zakkaru, spawn of Makkari, the dark one who demands sacrifice... his father forced from Zul'Farrak, his ascension interrupted... he will taste blood once more...
Go, <class>. Zakkaru has Sang'thraze. Ya not be wanting him to keep it, trust me.
