Welbie is torch-bearing spirit who's come to Camp after spending his lifetime helping people. Most notably he is the former guardian of Persephone's garden. Though first he helped a child of Hecate traverse the Underworld and then he helped a dog spirit endure life in the underworld before eventually being allowed to roam the over world. He's happy he's free - the underworld was getting a bit too warm for him.
Becoming Persephone's Guardian of the Garden Leaving the underworld
To marry Kipton
Coming to Camp
Leaving Persephone Being cursed so whatever flower he touches dies
On the surface, Welbie is caring and generally a kind person. Selflessness his his biggest trait and he likes to make other people smile in general. He also seems to be a very patient person who refuses to rush somebody. WIP On a deeper note, Welbie is bitter about what Persephone did to him and as such he feels some sort of resentment towards her. He is also described as being cunning by Persephone, mentioning that his appearance often helps him get what he wants. WIP
Welbie's creation and existence is surrounded by helping others. When a child of Hecate was venturing into the Underworld for personal reasons on their own, Hecate didn't want to take any risks when it came to losing the child (she and Hades were on bad terms due to a series of arguments) and as such, she created a torch bearing spirit to accompany the child through the underworld safely. Although there was some trouble along the way regarding Hades, Welbie eventually fulfilled his mission of successful guidance and Hecate began preparing him to go to Camp.
As Hecate's preparation went ahead, she noticed that a dog spirit named Kipton had been abducted and had been forced to work for Hades and felt negativity surrounding the ordeal, so instead of Welbie going to Camp, Hecate told him to remain in the Underworld to overlook the relationship between the two and report back to her every so often.
During this time Welbie was appointed with the job of guarding Persephone's Garden from time to time for astray souls, some of which aimed to destroy the garden. It was here that Welbie first got a glimpse of his main mission.
Throughout his time in the Underworld Welbie got closer and close to Kipton and always reported back to Hecate every week or so. Hecate, pleased with his work, offered the reward of leaving to Camp to which Welbie declined, stating that he still had a job to do for Persephone. Welbie remained in the underworld for another few months until one day where he was distracted by a rogue spirit who needed help getting to Asphodel. It turned out that the spirit had been used to distract him and as he did so more spirits came in and wrecked the goddess' garden.
When Persephone found out she was furious and ordered Welbie to go to Camp. In addition, she cursed him so that any flower he touched died, hoping that he couldn't find happiness for a long time.
