The voice in the pit turned out being the titan, Kronos.
I don’t know
That Percy almost died because of the pit scorpion.
The two things that the voice from the pit wants from the Percy include the bolt, and using Percy to get it out of the pit.
Kronos of course!
Kronos
in the last chapter of the lightning thief, Percy, Annabeth and Grover return home to camp with a great welcome. they get to attend a big feast and wear laurel crowns and burn shrouds. the Athena cabin makes Annabeth a grey silk shroud with an embroidered owl and the Ares cabin makes Percy's. the one that the Ares cabin make Percy is a bed sheet with x'd out smiley faces. afterward Luke and Percy go to the forest to relax on the last day of camp and Luke tries to kill Percy with a pit scorpion that can kill in 60 seconds. Annabeth takes Percy's advice and ends up going home for the year.
Yes. Percy hears a voice from a deep pit in his dreams, which later turns out to be Kronos
That Percy almost died because of the pit scorpion.
Kronos is the King Titan. The titans ruled in the age before the gods. The titans were the gods parents, but the gods disagreed with the titans ruling. So the gods overthrew the titans, and Zeus scattered the remains of Kronos into Tarturus, the deepest pit in the Underworld.
The two things that the voice from the pit wants from the Percy include the bolt, and using Percy to get it out of the pit.
Percy is a half blood and Hades stole Zeus's Master Lightning Bolt. and Hades framed Percy and put the lightning bolt in Percy's backpack, and he saved the world from having a world war 3. (against Olympus and the Underworld.)
no or else it will explode
Kronos of course!
Well not exactly. Zeus was just blaming Percy for the theft. The real villain was the thing in the pit. Luke was working for it. If you have read all of the books, I could put a name to it but I don't want to give anything away to those who haven't read it.
Kronos
Read the book.
No, it is highly unlikely. More people are killed by lightning every year than by pit bulls.
The earthing spike and earthing conductor and the earth pit to which the earth conductor is connected to.
