The Traveler

The Traveler is a trickster deity worshiped by Jester. 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.

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, in the dark space of the hood, there were verdant irises.

Traveler - "I'm so sorry she's not aware that you're here now, but you're with friends."

Jester - "Okay. Do you think you could help me, though?"

Traveler - "Child, I think I help you quite a bit already."

Jester - "I know. You do."

Traveler - "What do you need?"

Jester - "I don't know how to let her know-- I don't know what to do."

Traveler - "I think the more deeds you do, the more lives you change, the more confident brats you break -- She'll find you."

Jester - "Okay." pulls out the pamphlet. "Look what I made for you!"

Traveler - The hand pulls back and takes the pamphlet. "Hmm. Adorable."

Jester - "People are going to worship you like crazy."

Traveler - "You know what to do, then?"

Jester - "Yes! Okay. I missed you."

Traveler - "I'm never far."

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 Critical Role: 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". 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.
