Born to a Hive bloodline that dwells in the depths, Drehzzek a type of Graeph that's evolved to hunt a specific type of prey - Merkanlos. From afar a lurker Graeph can be mistaken for a Merkanlos, and they use this deception to their advantage. Sometimes the familiars that Merkanlos have are also fooled by this, and take a Graeph on as their bonded. Drehzzek, however, made the decision to eat one of those creatures and none have approached him ever since. (He was curious as to what they'd taste like, and was disappointed to discover they were tasteless.)
He has all the abilities of a normal Graeph, but can endure the pressure of deep sea with more ease than others. He's also able to breathe and survive in the depths, and is immune to deep cold.
