Some of Shroom’s lore:

Shroom is an acrobat that actually signed up for the job with her own will. She’s a very gentle motherly person though she can be very violent at random moments in time. No one knows why that happens or why she actually signed up for this awful circus but she does acrobatics very well. She’s 21 and went to the circus in her town after being in a forest  before stumbling into the tent where she met the ringmaster.
