What appears to be a frail old man on his steed is, in truth, a Fundamental, the Keeper of the Light. Ezalor's staff Illuminates the darkest corners, banishing evil from the realm. He replenishes his companions with Chakra Magic, while casting a Blinding Light over the land, causing attacks to miss. Heads turn to stare at a mysterious shimmering orb, unable to look away as the Keeper's allies encircle foes hypnotized by the flickering lights of the Will-O-Wisp. Effortlessly weakening his foes, Binding them to the primordial light. Revealing his full power, he enters Spirit Form, riding forth in all planes at once, Recalling his allies to further press the assault.

Bio

[edit]
They say twas I who carried the first light into the universe. They might be right, I can't quite recall.
▶️  Ezalor, the Keeper of the Light
Aliases:
Keeper, Ezalor, KOTL
Upon a pale horse he rides, this spark of endless suns, this Keeper of the Light. Ezalor long ago escaped the Fundamental Plane, separating from the other ancient forces to which he was bound within the great Primordial harmony. He is a power grown sentient in the dawn of the universe, and now rides forth in all planes at once, one step ahead of pursuing chaos, bearing his gift with him at the end of a radiant staff. His majestic truth lies hidden beneath the outward appearance of a slightly doddering old man who barely stays in the saddle. However, when faced with the challenge of chaos, or the forces of darkness, his primordial light bursts forth, and his full power is revealed, transforming him once again into a force to be reckoned with.

Trivia

[edit]
  • Ezalor's design in Dota 2 makes several references to Gandalf, an iconic character from "The Lord of the Rings" book series.
    • His clothing is almost purely white, similar to Gandalf's attire.
    • Illuminate's wave animation are a group of stampeding white horses. This is similar to the spell Gandalf cast on the torrent of water, at the ford of Bruinen, in the first book, "The Fellowship of the Ring". Additionally, it has similarities to his reinforcements at Helm's Deep during the second book, "The Two Towers". This is also depicted in the splash art, with Ezalor taking Gandalf's place at the head of the charge.
    • The Mana Leak cast line ▶️ "You shall not cast!" is a reference to one of Gandalf's most famous quotes: "You shall not pass!"[1]
    • The unused Mana Leak cast line ▶️ "Run! Run, I say!" is a reference to another one of Gandalf's famous quotes: "Fly, you fools!"[2]
    • The respawn lines ▶️ "Ezalor... I think that's my name." is a reference to Gandalf "respawning" as The White: "Gandalf? ... Yes ... That was my name ... Gandalf the Grey."
    • One of Ezalor's cosmetic items, the Wise Cap of the First Light makes him look even more like Gandalf.
  • ▶️ "Kundalini!" and ▶️ "The serpent of illumination stirs!" come, as well as the term "Chakra" is derived from Hinduism. Kundalini is described as a dormant inner strength, or "sleeping serpent waiting to be awakened".
  • Enigma, Chaos Knight, Keeper of the Light, and Io together represent the four fundamental forces of the universe with Keeper of the Light representing the weak nuclear force, the force responsible for the light of stars and suns, including the sentient sun Phoenix.
    • His Solar Bind and Mana Leak abilities reflect his theme of radioactive decay. As the name implies, it is the decay of an unstable atomic nucleus by radiation, the transmission of energy. Hence, the spell's ability to drain move speed or mana (energy) when an opponent moves (transmission).
    • Enigma's lines upon killing him further reinforces this when he says ▶️"Ezalor, your decay is now complete." and ▶️"Ezalor, the weak and infirm." which references radioactive decay and the weak force itself, respectively.
  • ▶️ "And chaos fled!" may be a reference to a bug that can occur when fighting the final boss of Final Fantasy, Chaos, as the player can win the fight without damaging him (he simply just fled).
  • ▶️ "I'll tell thee everything I can, there's little to relate." and ▶️ "Very gladly will I drink your honor's noble health." are quotes of the poem by "Haddock's Eyes" by "Lewis Carroll", a poem about a very odd old man.[3]
  • ▶️ "I'll forego green girdles and questing beasts, for all such knightly trifles pale before the light." is a reference to the book "The Sword in the Stone".
  • Visage's rival line towards Keeper of the Light ▶️ "You shall not pass!" is a direct quote from "Gandalf", a character from "The Lord of the Rings". This reference is due to the similarities between Keeper of the Light and Gandalf.[4]
