Cronin’s cat is a construct that beckons to Archmage Seer Cronin as his eyes and ears in the party. Its exact mechanism for reporting back to Cronin is unknown but it sometimes goes back to Cronin for a period of time. The group is instructed to let it follow them around unobstructed unless they need to hide it out of necessity.
Cronin’s cat seems to follow around particular party members, and changes its appearance based on who it follows. When it followed Julien it appeared as a black cat with one eye. Following Elan, it appears as a white cat with two eyes.
