Keeper of the Light

Ezalor the Keeper of the Light or "KotL" is a ranged Intelligence Hero famous for his reputation as a one-man support team. Supporting his allies in need, and push unguarded lanes with ease, Ezalor is a very valuable ally for any team. Having a variety of useful abilities, he can channel a powerful globe of intense light that can heavily damage an army of enemy creeps in the lane, allowing for an easy push; and manipulate the mana around him, restoring mana for himself and his allies or drain the mana out of his enemy. His Ultimate allows him to gain his full power, giving Ezalor access to 2 sub-skills and an improved existing ability, giving him six different abilities in total.

Trivia

 * 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 now almost purely white, similar to Gandalf's attire.
 * Illuminate's wave animation are a group of stampeding white horses, similar to Gandalf's 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.
 * One of Mana Leak's cast responses, "You shall not cast!", is a pun on one of Gandalf's most famous quote "You shall not pass!".
 * One of his spawn lines, "Ezalor... I think that's my name." is likely a reference to Gandalf "respawning" as The White: "Gandalf? ... Yes ... That was my name ... Gandalf the Grey."
