In Bonfire, I remember there was once this user whom adopted at least 10-12 people, myself included. Everyone ran around the map, and it was quite a fun time. Not so much recently, but on occasions after that event, I would see this user around the maps and have a small chuckle at the silly circumstances that occurred. Fun times. <3
Regarding both Mate Centers and Adoption Centers, their numbers are a bit fewer compared to the ones a few years ago, although I do see Mate Centers from time-to-time (Adoption Centers, not so much). I saw a MC just this evening, in fact. c: The Mate Centers and Adoption Centers both began with a person deciding to be imaginative and to create something new out of the Feral Heart experience, and it eventually became something that users new to Feral Heart soon become knowledgable of. The more people who take initiative to create MC and AC characters will give it the potential to sustain and become more commonplace. Since the majority of MCs and ACs originated in Bonfire Island, the renovation/replacement of the map may have dispersed some of the ideas that were popular in that area, so perhaps it will take a bit of effort and innovation from the users that still recall those FH user-inspired concepts to instill the concepts in areas of the new maps.
