Where players actually talk
The studio puts one link in the news posts: discord.gg/fQGevMS3EF. The invite record read for this guide showed a server named Legend of Defenders, about 804 members and 260 online, and the invite does not expire. Those counts move. I am dating them to 5 Nov 2026.

- Reddit: a search for the quoted title did not surface a dedicated subreddit. Posts that exist are scattered reviews, sale notes, and piracy. This page does not link the piracy ones.
- Bahamut: a search for 守城英雄傳 returned thousands of hits for other "英雄傳" games. The first page of results was not this game. I will not pretend there is a board.
- DCInside: two posts in the indie-game gallery on 4 Nov and 5 Nov 2026. No dedicated gallery.
- Steam discussions: the hub exists on the app. Threads include real questions about rarity letters, 3x speed, locked heroes, and slow progress. Those questions are why several cells on this site stay empty.
- No official X account was found. x.com/KaiPlayStudio returned not found. I am not inventing a handle.

Language hubs on this guide point Traditional Chinese readers at Bahamut's absence and Korean readers at those two DCInside posts. The Discord is still the only place the studio asks people to report bugs. The 4 Nov patch post says so again.
