Ahoy! I come bearing an IRM for Nanci Grackle! This page was written primarily by myself and abbasnail, with help from other members of the Georgias community. For an overview:

Nanci Grackle (he/him, they/them, ze/hir) is a mad ornithologist, whatever that entails, that has lived in our shadows for most of his Blaseball career.
Most of Nanci's history before Atlantis is unknown, but he frequently makes a lot of weird off-hand comments that seems to suggest bits and pieces of his background.
Nanci arrived in Atlantis when trying to study a flock of seagulls, accidentally tripping over the side of his boat, and falling into the ocean. He hates it here.
Nanci works at the Atlantean Facility for Interdimensional Studies and Hypotheses, but his questionable research methods have given him a lot of flack from his peers, particularly Niq Nyong'o.
Nanci joined the Georgias' active roster in Season 20, and quickly became subject to allegations of vampirism after draining blood from Richmond Harrison. When confronted on this, he continued to only give vague non-answers.
Nanci seems uncomfortably comfortable with necromancy, encouraging Flattery McKinley to help him in raising an army of undead muppets, which would eventually work as Atlantis' Phantom Thieves' Guild.
