The Traveler

The Traveler is a trickster deity worshiped by Jester in the Wildemount Campaign of Critical Role.

The Traveler 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.

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.
 * The Traveler is not mentioned in the "Tal'Dorei Campaign Setting" as either one of the Prime Deities or one of the Betrayer Gods. It is possible that The Traveler is worshiped exclusively in Wildemount, or at least is not heard of in Tal'Dorei.
 * In the Dwendalian Empire, "worship outside the approved idolatry is met with imprisonment". It is possible that the Traveler isn't one of the approved deities and that worshiping him may be illegal.
