|First appearance||Betrayal at Falador|
|Last appearance||Legacy of Blood|
Ebenezer was born in Varrock. In his youth, Ebenezer reveals he tried to become a magician, but felt it wasn't suited for him. He still has the runes he had from his youth into his late years. Sometime in his life, he was married, but his children died in infancy due to small pox and his wife Eloise died in childbirth. They were buried in the garden of his house in Varrock, which he permanently left in 5.145 due to his grief. He travelled westwards and received a travelling cloak from his friend Sally against the rain.
During one of his travels, Ebenezer encountered the young werewolf, Gar'rth, who fled from his family in Morytania and was stealing from farmers to stay alive. Knowing of his condition and background, Ebenezer adopted Gar'rth and took him to Taverley to request help from the druids. There, he met Castimir, an apprentice wizard from the Wizards' Tower, who becomes his partner in a debate between magic and science through out the book. The druids of Taverley developed a potion to help stabilise Gar'rth's condition. However, the potion grew more powerless every time its used, forcing Ebenezer and Castimir to head to the Monastery to request the help of the monks. Along the way, he met with Kara-Meir, Squire Theodore, and Doric at Gunnarsgrunn, as well as Arisha, the head priestess from Gunnarsgrunn.
Battle of the MonasteryEdit
While attempting to cure Gar'rth of his lycanthropy, the monastery was was attacked by Zamorakian forces made up of Kinshra and Chaos dwarves led by Lord Sulla and Gar'rth's uncle Jerrod. Ebenezer worked with Castimir in order to defeat Jerrod through a combination of entanglement magic and explosives and escape the monastery in order to bring word to Falador.
Siege of FaladorEdit
Ebenezer was swept into the Siege of Falador, using his mind to find defensive strategies to defeat the approaching army. One such device he created was pig fat bombs, created by coating bales of hay with pig fat and using catapults to throw them into the goblin forces, setting them ablaze through flaming arrows or fire spells.
Discovering the traitor of the White KnightsEdit
Ebenezer aided Sir Tiffy Cashien and Marius in an attempt to hunt down a turncoat among the ranks of the White Knights. They determined that the traitor was Sir Erical, a retired knight who had returned to train the peons and squires. They tracked him down to the Falador Sewers, where they found his body. The true traitor, Sir Finistere, trapped them, but due to the unforeseen intervention of Sir Pallas was unable to kill them. Ebenezer broke them out of the trap and Marius slew Sir Finistere.
Epilogue of Betrayal of FaladorEdit
After the battle, Ebenezer is planning to help the nobles of Falador regain their valuables they hastily threw into the moat of Falador. However, in order to do so, he must head to Varrock to purchase the necessary equipment and chemicals. Due to the large income of money and the feeling the other members of the party deserved some sort of reward, Ebenezer adopts Kara Meir, Squire Theodore, Castimir, and Gar'rth and was going to add Doric as an heir too, but Doric was older than Ebenezer and was rich in his own right. He promises to meet with everyone at Varrock on Midsummer's Eve.
Return to CanifisEdit
Ebenezer arrived in Varrock with Doric for the Midsummer Eve festival. While in Varrock he caught up with his old friend Albertus Black and Sally, and demonstrated some of the wonders of science to Doric.
During the Midsummer Eve feast, Ebenezer noticed Gar'rth acting more hostile and reckless and confronted him. Gar'rth confessed that he felt like an outsider among the group, but was distracted by the Wyrd attacking the palace. Gar'rth, along with Castimir, Sir Theodore, Captain Rovin and others, attacked the Wyrd. However, Gar'rth's secret was revealed and he was imprisoned for being a werewolf. The stress of Gar'rth's arrest proved too much for Ebenezer and he suffered a heart attack and slipped into unconsciousness.
Over the next while Ebenezer continued to slip in and out of consciousness, and was not always lucid when he was awake. When he finally recovered enough to stay awake and lucid, he learned that Gar'rth had left but had left him a note, as had Theodore, Kara-Meir, Doric, Castimir and Arisha. Determined not to remain a helpless bedbound old man, he threw himself into determining the actions of the Wyrd, figuring out that the children taken all had birthmarks that corresponded with a picture at Paterdomus.
Legacy of BloodEdit
When the embassy returned from Morytania, Ebenezer was devastated by both the losses of his old friend Albertus and Gar'rth and of the theft of Albertus' body by Zamorakians. Too infirm to be of much use elsewhere, Ebenezer guarded Felicity as best he could, even during the Battle of King Botolph's Tower. Ebenezer realised what had happened to Albertus in Morytania and tried to fight the vampyre his friend had become, but his efforts were futile. He was beaten and left alone in the collapsing tower, and Albertus took Felicity to be sacrificed.
In the last chapter it was mentioned the group (Kara-Meir, Theodore, Castimir etc.) attended his funeral.
To Ebenezer, Gar'rth is the son he never had. Since all of his children died in infancy due to smallpox, Ebenezer sees Gar'rth as his second chance at being a father.
Throughout the story, Castimir and Ebenezer hold a debate over magic and science. Despite being rivals, they are very good friends.
Albertus and Ebenezer are old friends, even to the point where Albertus lives in Ebenezer's Varrockian house following his departure. When Ebenezer is taken ill during Return to Canifis, Albertus goes in his place.
