Whether he is calling Pippin a fool of a took or standing toe-to-toe with a Balrog, Gandalf always had a way of rising to the occasion and being the voice of reason that you wish could have existed in your real life.
Now there is not a vast amount known of Olórin's earliest years, except for the passage we get from the section of the Account of the Valar and Maiar according to the Law of the Eldar.
But of Olórin that tale does not speak; for though he loved the Elves, he walked among them unseen, or in form as one of them, and they did not know whence came the fair visions or the promptings of wisdom that he put into their hearts.
In later days he was the friend of all the Children of Ilúvatar, and took pity on their sorrows; and those who listened to him awoke from despair and put away the imaginations of darkness.
So we can see from this, Olórin was not just the wisest of his kind, but also one of the few to embrace the idea of pity and patience and became fascinated with the Children of Ilúvatar.
And so, it was around the year 1000 of the Third Age that Olórin arrived to the lands of Middle-earth, having left Valinor to arrive at the Grey Havens, also known as Mithlond.
He was one of the most gifted with the skill of foresight and was honored to be given one of the Three Elven Rings of Power by Celebrimbor, being the ring Narya.
Re-embodied during the Second Age on a similar mission to that of the Istari, which in fact, in Tolkien's later writings, was believed to be around the same time as the coming of the Blue Wizards, which was around the year 1600 of the Second Age.
For he dwelt in no place, and gathered to himself neither wealth nor followers, but ever went to and fro in the Westlands from Gondor to Angmar, and from Lindon to Lórien.
For they deemed him (though in error, as has been said) to be of Elven-kind, since he would at times work wonders among them, loving especially the beauty of fire; and yet such marvels he wrought mostly for mirth and delight, and desired not that any should hold him in awe or take his counsels out of fear.
After being in Middle-earth for around 100 years, Gandalf and the others of the Istari discovered there was an evil shadow growing within the forest that used to be known as Greenwood the Great.
Despite this, according to Appendix B at the end of The Lord of the Rings, it would take until the year 2063 for Gandalf to finally go and investigate Dol Guldur himself.
Although initially Galadriel had wished for Gandalf to be the leader, but due to Gandalf wishing to never set down roots and being able to continue wandering as and when he wished, he declined this offer.
In the following years, Gandalf visited many places, and it was around this time that he first came across the people known as the Hobbits in the Shire.
Until he took it upon himself to look for the Dwarf King Thráin II of the Lonely Mountain, who had disappeared while camping under the eaves of Mirkwood.
Here he found Thráin within the pits, but not just this, Gandalf made the important discovery here that the Necromancer was in fact not one of the Nazgûl.
He heard word that Smaug the Dragon had claimed Erebor and destroyed the town of Dale, which led Gandalf to worry Sauron would try to create an alliance with this great beast to further enhance the strength of his forces.
And this is where he received convenient word that the exiled Dwarf King of Durin's Folk, Thorin Oakenshield, was in fact hatching a plan to retake the mountain.
Therefore, not long after, Gandalf turned up at Bag End with several Dwarves behind him and persuaded the Hobbit Bilbo Baggins to join their quest as their burglar.
However, by the time he finally got back to this area, the company had escaped, got to Erebor and prepared for an attack by the Lake-men and the Wood-elves.
After this battle, Gandalf would journey with Bilbo back to the Shire by way of Beorn's and then Rivendell to meet once more with Elrond to discuss all that had happened.
This in turn meant Saruman learned for the existence of the Hobbits and the Shire, noting specifically that Gandalf had a great interest in these people.
And so, after warning Frodo to never use the ring, but to keep it safe and keep it secret, Gandalf headed into the wild to hunt once again for the creature Gollum to maybe find some answers.
Conveniently, Gandalf would then receive word that Aragorn had succeeded in locating Gollum, and so he journeyed to Mirkwood to interrogate him for the answers that he hoped for.
It is now April of 3018, and Gandalf has reached the Shire, and he manages to confirm with Frodo once and for all that this magical ring is indeed Sauron's old One Ring.
But now at Isengard, Gandalf learns of Saruman's true intentions, and after rejecting the chance to join him, becomes imprisoned upon the peak of Orthanc.
Gandalf once again headed for the Shire with as much speed as he could muster, and upon his arrival, he learns that Frodo had already left when Gandalf had not returned in time.
And so he makes for Bree, where he learns that Barliman had never sent his letter, but somehow Frodo and his friends had still managed to come under the watch of Aragorn nonetheless.
After a night's rest in the inn, Gandalf made for Weathertop, as here he could get the best view of the surrounding lands to try and observe what is going on.
In time they would reach the Chamber of Mazarbul, where the Fellowship discovered that Balin and a party of Dwarves had attempted and failed to reclaim this kingdom of their ancestors.
Right at the Balrog's feet it broke, and the stone upon which it stood crashed into the gulf, while the rest remained, poised, quivering like a tongue of rock thrust out into emptiness.
Upon reaching the top, they fought for two more days and nights, but eventually Gandalf managed to throw down his enemy onto the mountain side, however, this took the last of Gandalf's strength.
Saruman had become trapped in his tower after the Ents of Fangorn, along with Merry and Pippin, had ruined the outer walls of Isengard and the Orcs that stayed there.
Now that there was definitely no hope for Saruman, Gandalf's mind quickly turned towards Gondor, he knew Sauron would launch his attack at any time, and they had to go to their aid.
Soon after, Gandalf would ride out of the gates on Shadowfax to drive away the Nazgûl that were trying to stop Faramir's forces retreat after losing Osgiliath.
Gandalf did all he could to encourage and lead the men of Minas Tirith in their defense, countering the fear that the Nazgûl instilled in their enemies, but there was little he could do to defend against catapults.
There was no rest for Gandalf though, as Pippin found him and told him of Denethor's plan to burn both himself and Faramir alive as grief had overcome him.
As for the siege though, after the arrival of both the Rohan force and the force brought by Aragorn from the southern fiefs, the forces of good managed to break the siege and wipe out Sauron's attacking force.
Again though, there was no time to rest after this battle as Sauron still had power, and so the leaders of the remaining men elected Gandalf as their leader for the remainder of the war.
Gandalf knew that whatever they did would be in vain if Frodo was to fail his mission, so they needed to do anything they could to help him complete his quest.
He advised they took their armies north to the Morannon and distract Sauron so that Frodo's passage, which would most likely be coming from the opposite direction, could go hopefully unnoticed.
Upon their arrival, they were met by the Mouth of Sauron, who attempted to intimidate the force by revealing Frodo's Mithril vest to them, saying that they have captured and tortured the Hobbit that it is belonged to.
And so, after traveling back with the Hobbits to the borders of the Shire, Gandalf would go off to spend his time to talk with good old Merry, Tom Bombadil.
The Wizard that was known as Gandalf returned to being the Maiar known as Olórin, and that is where the journey of this divine spirit ends from what we know.
