Not sure if these four are Canon in the Hopeverse yet but I certainly had fun drawing them, also I wanted to point out that this may or may not be my Final coloring style. Anyway, meet Courtland (son of Sombra and Honey blossom) and his crew: Magnar (the Unicorn stallion on his left), Hestia (the Earth pony mare on his right) and Delta (the pegasus mare above).
these Five (they are accompanied by a bard, who's not in the picture because he doesn't have a design yet) are a team of monster Hunters, their purpose is to track, hunt down, and either tame/kill any creature that's causing trouble in Equestria, they mostly tame the creatures and later release them again, but if the creature is deemed to be "too wild/evil" it'll be killed, this are extreme cases and they'll only try to resort to that if they have tried everything else first, however, any Umbrum they capture is an immediate kill.

From left to right:

Magnar: the "Fighter" of the group, he's all about marching into battle with no regrets: Magnar is bold, extremely loyal, a bit old fashioned, cocky and certainly doesn't know when to shut up, which is one of the reasons he's got the most scars. He secretly fears silence so he talks to himself a lot, Courtland is sorta scared that an Umbrum has gotten into his head.

Courtland: Court is the Leader/Wizard of the Group, although he doesn't talk too much, Court is Quiet, Cold, Smart, Serious and Objective on the outside, yet the few ones that truly know him can see that he truly cares for others, but is afraid to get too attached.
Court Started this group/Quest when he Hear from his little cousin (John) that a lot of ponies/creatures in Ponyville were getting "sick" and upon the discovery that it was the wrongdoing of the Umbrums he took it on himself to fix it, after all; It's kinda Court's fault.

Hestia: the "Brains/planner" of the group, she's very studious and organized (despite her tail saying otherwise), she's the one that is in charge of the documentation and researching in the latest Books Fluttershy "of Kindness" releases about Magical creatures.
she has the "kindest" approach when taming the Creatures.

Delta: the healer/doctor, her job is to make sure is that no one is hurt too bad, Delta a is motherly but tough mare, she cares for others and wont take No for an answer.
