I'm glad you liked the game. What part you liked the best?
Also, the game doesn't have a discord server since I don't think it is popular enough, plus I don't use discord that often.
However, Sinathir has its own section on a discord server that focuses on princess maker and other raising sims: https://discord.gg/55QERT5U
As I said, I don't use discord very often, but I check the Sinathir section here atleast once a day.
