List of hostile NPCs
- The Lernaean Hydra was a multi headed creature slain by Heracles (Labors of Hercules) for his second labor.
- All hydra bosses have a three part name, with one name representing each head. Some or all of them are distorted and/or re-ordered phonetic versions of common expressions. For instance, Nayl Klaw Tuthan is a phonetic rendering of the idiom "nail, tooth, and claw."
- During their idle stance, the left and right heads are fighting with each other.
