A monster Lich met adventuring. Only the dead can understand it, which includes Lich and Vie.
Their name cannot be pronounced, so Lich and Vie nicknamed them "Imonno" aka and "I don't know" sound.
Vie is lowkey terrified of it, and doesn't get along well. Everyone else is highkey terrified-- except Lich, who's not scared at all, and LOVES Imonno. They often do weird junk together.
Nobody knows much about Imonno other than it enjoys dancing.
