Emily claims she is here to heal and save the members of this community. The altercation with Delora has shown us that Emily is still ready to lash out at others at any opportunity.
She is a false healer, bound to bring only harm to the people she interacts with.
She is not a shaman, she is a fraud too blinded by her own ego to see she lacks every requirement for the title.
Do not trust this snake. She is vicious.
