Both of them serve as missionaries, trying to get other creatures to join their group to help become "enlightened" and sort their life out. They act all kind and perky, but a lot of ponies can tell that something si a bit… "off" with them.
They also work as healers and saleponies of the group. They help to create all sorts of essential oils and "miracle" cures (Lilly gathers the ingredients, Bramble s the one who makes them) that are often sold to a lot of gullible ponies.
Do you want to let these 2 pones in and help become "enlightened"? c:
