The Traveler

The Traveler is a trickster deity worshiped by Jester. As an NPC, the Traveler is portrayed by Matthew Mercer.

He seems to find enjoyment in mischief and pranks. When Jester rearranged all the books in a bookstore, she felt a sense of approval from her deity.

Jester keeps a sketchbook that she appears to use as a means of communicating her experiences to the Traveler, and as a way of worship.

Jester's holy symbol for the Traveler is a door arch and path.

Appearance
When the Traveler appeared to Jester in her room at the Pillow Trove in Zadash, he was hooded in a cloak of deep green. She saw verdant irises in the dark space of his hood.

Jester confided in the Traveler when she didn't receive a package from her mother at the Pillow Trove. He manifested and reassured her, explaining that Jester's mother was unaware of her location at that moment.

After Jester had successfully defaced and made her getaway from the Hearth of the Allhammer in Zadash, he made his presence known by taking a bite out of the caramel apple she had been eating.

Located among the many religious artifacts found in the Merrow lair, Jester finds two different iterations of the Traveler symbol. Despite having zero knowledge of anyone else worshiping or acknowledging the Traveler, Jester excitedly goes around to show everyone her find.

Trivia

 * The Traveler that Jester worships is not the same as the one in the Eberron setting of Dungeons & Dragons, as Matthew Mercer confirmed that they only share the same name. He also said that the Traveler may not necessarily be a god.
 * In the Dwendalian Empire, "worship outside the approved idolatry is met with imprisonment". The Traveler isn't one of the six approved deities and worshiping him is illegal, though most citizens of the Dwendalian Empire seem unaware of his existence.


 * A common theory in the fandom is that The Traveler is actually Artagan from the first campaign, given new power and influence in this dimension.  The theory goes that, after Vox Machina completed their end of their deal with him and built a doorway from the Feywild to Exandria, Artagan took on the role of The Traveler in the hopes of finding a path to godhood.  There is some evidence that is commonly cited, including:
 * Jester's drawings are frequently described in a style that is very remniscient of Garmelie's (another form Artagan takes) prefered art style.
 * Jester's pranks resemble the pranks Garmelie had Vox Machina play as part of his deal when they entered Syngorn.
 * Artagan is commonly linked to the color green and the brief bit we've seen of The Traveler, the only physical description he is given is having green eyes.
 * The Traveler's symbol is that of an open doorway leading to a path, a possible connection to the doorway Vox Machina made for Artagan to crossover with.
 * His name is "The Traveler" implying he traveled from someplace else, potentially the Feywild.
 * The Traveler and Artagan are both powerful tricksters.


 * Another Critter theory is that The Traveler is one of the Betrayer Gods, in disguise. The Traveler seemed to recognize the magic of the Xhorhasian beacon, and Xhorhas is built upon the ruins of Ghor Dranas: the city of the Betrayer Gods.  If so, The Traveler is likely one of the Betrayer Gods of the Trickery Domain: The Chained Oblivion, The Cloaked Serpent, The Lord of the Hells, The Spider Queen, or The Scaled Tyrant.
