D.D.D

D.D.D is a powerful guild in Elder Tale. It is the largest battle guild in Akihabara and has more than 1,500 members, including many who are level 90. It is led by a Guild Master named "Berserker" Krusty.

Overview
This battle guild was famous for clearing Oracle's Tower some time long before the Catastrophe, which people from other servers thought would be impossible for Japanese players.

Alongside Krusty, D.D.D is under the joint leadership of three leaders, nicknamed the Drei-Klauen. However, the Vice-President withdrew from her position and it is currently vacant. The guild is organized in a way that each division can be autonomous and can operate in the event of Krusty's absence. Although for D.D.D, raiding is Serious Business and is organized under a strict military-like structure (complete with official uniform), it does not discriminate against low-level players and is open to everyone. Due to this, they are seen in a better light than the Black Sword Knights. The origin of the guild's name was Krusty randomly hitting his keyboard and hitting the letter D. However, because naming a guild with just one letter isn't allowed, he settled for D.D.D. After the Catastrophe, D.D.D began absorbing smaller guilds to increase its power, whereas guilds like its rival, the Black Sword Knights, imposed stricter membership requirements.

Three months after Krustys disappearance the guild began losing members due to a loss of his leadership. Other guilds absorbed these losses into their own ranks.
