|“||I've come to your land to chase an old acquaintance, but I end up spending most of my time hiding from him instead.||”|
Hoid is introduced as King Elhokar's Wit (court Jester); he plays the part of the king's weapon, tasked with insulting those that the king can't afford to personally offend.
He seems to be concerned about the future of Dalinar Kholin as he warns him that Sadeas is planning something at one of the King's feasts. Wit leaves the warcamps after this, first to visit Kaladin, then off to Kholinar.
During the exchange between Hoid and Kaladin, Hoid reveals that Hoid is not actually his name, but the "name of someone he[Hoid] should have loved."  It is also during this exchange that he reveals that he is a thief of sorts, and that his name is something he stole. A Worldsinger, and Sigzil's former master, he uses words and stories to influence those around him.
While introducing himself to Kaladin, Hoid relates that he began life as a thought, a concept, words on a page. And that this was something he stole, himself. He also reveals that another time he was named for a rock (shard?), a beautiful one that became worthless for his wearing it.
Hoid is present in the epilogue when Talenel’Elin (Talenelat in modern Alethkar) arrives in Kholinar. After Talenel’Elin falls, Wit remarks that the most important thing humanity values is "timeliness" and that he fears Talenel’Elin has arrived too late.
Hoid seemed rather unimpressed by the arrival of Talenel’Elin, even referring to him as "old friend." It is also interesting to note that Hoid just happened to be waiting at the spot that Talenel'Elin showed up.
Appearance, Personality and AbilitiesEdit
Physically, Hoid appears as a light-eyed, thin, tall man with dark black hair. Wearing a sleek black uniform and silver sword at his waist. He is equally at home being called Wit or Hoid, and his several appearances throughout the book indicate that he is a multi-talented entertainer and intelligent man. He shows his cleverness with words by insulting Brightlords at the King's Feasts. He demonstrates his storytelling ability by presenting the tale of Derethil and the Wandersail to Kaladin.
Hoid is described by his peers as having white hair, a clever tongue, and an arrowlike face. They note he dyes his hair sometimes and often wears a disguise which makes his true appearance difficult to ascertain.
- Worldhopping - Hoid is very good at manipulating Shadesmar. He can travel between worlds in the cosmere.
- Lightweaving - an illusion magic that is similar to, but not quite the same as, the Illumination Surge used by the Lightweavers. It is believed that he used this power during his storytelling with Kaladin.
- Allomancy - It has been long suspected that Hoid ate the bead of Lerasium he stole in "The Well of Ascention" and the scene in Shallan's flashbacks where he pours metal flakes into his drink, combined with confirmation that allomancy was used in Words of Radiance, seems to support this. 
- Feruchemy - Brandon has stated that Hoid's ability to always know where he needs to be is connected to Feruchemy in some way. However, we don't know how he obtained this power, or if he is a full Feruchemist or a Ferring.
- Awakening - We know Hoid was on Nalthis previous to the Stormlight Archive, and his comments about perfect pitch seem to suggest that he has at least the Second Heightening.
Hoid has been around forever, long before Adonalsium became the central plot of his story. He has not 'lived' all of those years, but has used some time dilation techniques. That said, he is far older (both in relative and real time) than a normal person can live.
Hoid is constrained by magic like everyone else, but he is far more adept at using it. He very good at using Shadesmar, the cognitive realm, connecting all the worlds in the cosmere, particularly to travel between worlds in the Cosmere.
Sanderson said he has an old short story from the early, early, early days where he's on a planet [from Dragonsteel] trying to figure out how the local magic system works.
Hoid has a bead of Lerasium, from the world Scadrial, a powerful magical metal that grants magical powers; and a Moon Scepter from the world Sel.
Hoid first appeared in Brandon Sanderson's 6th book, Elantris; next was in his 7th book, Dragonsteel, then in his 8th book, White Sand and has appeared in every cosmere novel except The Emperor's Soul:
- Elantris: Hoid is a figure within the Arelish underworld.
- InMistborn - 'Final Empire': Hoid appears as an informant who poses in guise of a beggar in capital city of Luthadel.
- In Mistborn - 'Well of Ascension', Hoid spends most of the book looking for the Well Of Ascension in the Terris homeland in the north. He is present when the Inquisitors destroy it and leads the evacuation of the Terris people to Luthadel. On the way back he is the Terris leader that Elend and Spook meet as they chase after Vin when she realises where the Well is. Once Hoid realises this to, based on his conversation with Elend, he worldhops to the Well and steals a bead of Lerasium. The footprints that Vins see leading up to Wells are Hoids and the smashed container is his doing. Hoid is not named in the book but is there to be picked out by description.
- In Mistborn - 'The Hero of Ages': Hoid again appears as an informant, but at the last second Vin decides not to meet with him.
- In The Emperor's Soul: Hoid is only referenced. Initially he was featured in the prologue speaking with the main character and setting some of the plot in motion, but it didn't fit and was cut before final revision.
- In Warbreaker: Hoid summoned by Lightsong, appears as a storyteller who performs for princess Siri.
- In Mistborn - 'Alloy of Law': Hoid appears as scruffy-looking "beggar in black" guy at the wedding dinner, but is not named. The events happening here are not of deep interest to Hoid, unlike the events in the original trilogy, so he plays a much smaller role here than in the original Mistborn trilogy.
- In Dragonsteel (unfinished): Hoid will play the part of protagonist and primary viewpoint. The plot will take place before all of the other books.
- Liar of Partinel (unfinished): The original Hoid is the recently deceased senior jesk and master Lightweaver. The Hoid featured in all other stories, called Midus here, stole the original Hoid's name, as mentioned above.
- Tentatively, in The Emperor's Soul: He could possibly be the Fool that got Shai captured at the beginning of the book.
