there's the pretty lacking wiki, otherwise there's only personal notes
if by 'final boss' you mean the end of Collapse and the Ceremony, then that's a mystery that's still yet to be unfolded. Vekoa got banished back into the groundsmindry core, the ceremony got interrupted, the Embassy collapsed, some escaped via movefriends or Tozik ejecting everyone. casualties still mostly unknown; Tozik (very probably) dead and burried within the Embassy, Kazki probably fled off Earth. Vekoa, the groundsmindry attendant, Malvi, the archivist you can talk to in Better Times via proxy, Miltza, Dozkallvi and others were absorbed into the Ceremony.
