|Base of Operations||Crystal Caves|
|First Appearance||"Cave of the Casterwills"|
Mallory is one of the ancient guardians of Nimue Casterwill and works alongside White, guarding the secrets of the Crystal Caves on the coast of England and protecting the current Lady of the Lake, Vivian Casterwill.
Mallory, along with White, attacked Dante Vale's team from a clifftop when the group was swimming to the coast of England. After Mallory's Icarus and White's Feyone were defeated by the team, they led Dante, Lok and Zhalia into a trap. During the intense battle, Mallory used Channelmight to revive his Pellinore Titan. The pair eventually overpowered the team but were called of by Nimue.
Mallory was present at the Casterwill meeting at the Fortress of Iron Will. He and White held Santiago back from going to find Sophie whilst on the Trial of Courage. He later fought against the Blood Spiral along with the rest of the Casterwill family in defending the Fortress of Iron Will. He was much dismayed at the death of Nimue.
In the final battle against the Betrayer and his Blood Spirals, Mallory and White were knocked out by Shauna whilst protecting Vivian Casterwill but she was stopped from finishing them off by Vivian, who invoked Mythras. Following the defeat of the Betrayer, both recovered after the battle.
Mallory fights side by side with White to defend the Crystal Caves from trespassers. Like his partner Casterwill guardian, Mallory is a skilled swordsman and can utilize an array of powerful Casterwill family spells.
