Wendigos are an Native American spirit/creature.
I think it could work if you had said wendigo being a traveler as Raven being a thunderbird is also a Native American creature and based on a deleted scene of Season 2 explaining his absence, he stated he was important and needed elsewhere making me think North America.
Especially base this mostly off my headcanon Hilda is set in an alternate 90s earth where human civilization co-exist with various mythical creatures from certain lands (Australia: Bunyip, Egypt: Sphinx, Greece: Centaur, Japan: Kitsune, New Zealand: Taniwha, Northern Canada: Akhlut, etc.) with Hilda obviously taking place somewhere in Scandinavia based on its Norse setting and creatures.
That and on Deviantart featuring art of the mapinguari in Hilda style supposedly as a traveler.
