Pebble is one of the children in Villagetown who attended school, hoping to achieve the rank of warrior and then captain. He's shown to be skilled in combat, surpassing Runt's skill. However, his moment of weakness came after he accidently drank a confusion potion when he attempted to murder Runt by exploding him in a shed with explosives, being defeated and creating a hole in the wall. Runt, the classmates, and the Legionaries successfully prevented a wave of zombies from invading the village.
Pebble was exiled from the village the next day, and disowned by his father, leaving all his worldly possessions to Runt. In the book spin-off Path of Exile, he manages to survive with zero items by looting the items of fallen adventurers and scouring the ruins of abandoned villages for items. He encounters the Skull Lord, shortly coming across the adventurer S.
Pebble used to wear a lime-green robe until exiled. Now he's clad himself in obsidian armor. He is a male villager with most of the typical male villager features.
Pebble was seen by a bully by both Runt and Max, ripping their gradebooks and sabotaging their projects. He and his friends were seen harassing Runt, and often trying to steal his items. He has a cocky attitude, belittling Runt's achievements and flaunting his own, as seen when he received war hero status and a new cape. What really happened behind the cocky bully war hero image was a toxic upbringing. Pebble's father often placed high expectations on his son in hopes he would become the mayor one day, a power struggle which Pebble didn't understand.
When Pebble met Runt in the dungeon, he was no longer a bully, and was nicer to Runt. Having lived in the wild and had to fend for his life, trivial fights and petty squabbles meant nothing when faced with starvation, violence, and even death.

Despite all his best efforts, his dad always viewed him as a failure to the Graybanner family.
Pebble ended up spending most of his days in school taking out his pain on others, especially the noob named Runt (refer to 8-Bit Warrior books 2-4)
However, his life took a sharp turn when Herobrine began invading his dreams, trying to convince Pebble that Runt was a danger to the village.. Pebble ignored this until one day when he spied Runt playing with Jello through his bedroom window.
Since mobs have been raiding Villagetown more than ever, and Urf, one of the former elders, betraying the village and turned to Herobrine’s side, people became cautious about who they spend time with. As a result, after Pebble saw Runt playing with Jello, he had a conspiracy that Runt was also a spy and harmed the village unless he was to be killed.
That night, Urf put a confusion potion which he named a healing potion in Pebble's inventory. The next day Pebble drank the confusion potion under the impression that it was a healing potion
One night as Runt was walking back home, Pebble, still under the effect of the confusion potion, along with his gang grabbed him and took him to a room next to the eastern wall. They threw him into a hole, placed TNT into the outer walls, and fled the blast-zone. Runt survived and he climbed out of the ’valley‘ that was created under the eastern wall after the explosion and clashed with Pebble in a fierce duel. Runt won due to the enchantment from his cloak, only to see a zombie horde trying to exploit the new hole in the defense.
After clearing the invasion, Pebble realized his mistake and offered everything he had to Runt. He then admitted to the mayor that he was to blame for the sabotage, and was exiled for his crimes.
Afterwards, he spent weeks wandering the wilds, barely surviving on random item piles that were once other people. If it wasn't bad enough, he was also being pursued by a band of Pigmen trackers, and later managed to kill them, one by one. Herobrine also appeared to him in a dream, and tried to entice him to join the monster army. Herobrine told Pebble that he was a descendent of a Highborn(Villager) king in Path of Exile. He later met S, who gave him obsidian armour and two redsteel axes.
Later, while exploring the Tomb of the Forgotten King, Pebble and S encounter Breeze and Runt while fighting Felhounds. They defeat them, and move on to the boss room. They encounter Urf, who reveals himself as a Nethermancer working for Herobrine and soulshifts into Nethersoul, the boss.
After defeating Nethersoul/Boss Urf, Pebble and S accompany Breeze and Runt back to Owl's Reach, then set off to light the beacon at the Temple of the Sapphire Flame, at which they succeed.
