I can't remember the name of this game

Hey! I used to play a game a while ago, about 6 ish years. I can not for the life of me remember its name. I have tried googling the specifics that I can remember but I've had no luck. Just wondering if anyone knows this game. It was a free multiplayer rpg game that had quests, goals, boss-like creatures, different realms, and spirit animal-type creatures that would fight alongside you. It was a fantasy-styled game. You could have different weapons and different animal sidekicks, some were mythical creatures rather than animals. I'm trying to remember more details but I can't as it was so long ago. Would be very appreciated if someone could let me know its name!
