Black Sword Knights

Black Sword Knights is a guild in Elder Tale that only accepts members that are level 85 or higher.

Overview
Black Sword Knights is a guild founded by Black Sword Isaac. Known for its policy of only accepting members that are level 85 or higher, Black Sword Knights is currently one of the top battle guilds in Akihabara.

After the apocalypse, the Black Sword Knights are unable to dramatically increase their membership (a strategy employed by the rival battle guild, D.D.D), so they focused on quality over quantity. Namely, this involved increasing the level of their current membership above the previous 90 maximum level cap.

To this end, they utilized low-level player's EXP pots, which they bought from Hamelin.
