See. Er.

The conversation was cut short by the new voice, which came from nearby the Hydra. Dreth looked on as a door, which had been artfully hidden in the cliff side, opened and a small figure stepped forth. 

"Fido! Heel! And you! Stop that!" The newcomer pointed at Percy, who paused, the black sword wavering in his hands. "Honestly, I have to feed all these heads you know!"

Dreth strode forward quickly and, reaching around from behind, neatly plucked the blade from the zombies' hand. Immediately a wave of bloodlust swept over him, and he raised Darkblood into a fighting stance before managing to overcome the weapons' influence and lower it again. 

Percy collapsed. "Oh, thank you! I thought I'd die of exhaustion!"

"You can't die of exhaustion, you're undead," snapped Dreth, turning to the short figure glaring at them. "Who are you then?" he asked.
