All From Different Places

There exists a world beyond the one we commonly know. A world of people with animal ears and tails. A world of mermaids and bird-people. All of these people have extended life spans. The average life expectancy for these creatures is around 1,000 compared to the usual 100 for humans. Back in the day breeding between races was frowned upon so a magic system was put in place. Every person was granted a soulmate from a different race. Sometimes someone had more than one soulmate!
