Hamelin

Hamelin is a guild in Elder Tale.

Overview
Hamelin is a medium-sized guild located in Akihabara. Its policy is supposedly "mutual assistance for beginners" and has recruited many of them during the Apocalypse. However, their true intention was to collect the beginners' EXP Holy Water and sell them to battle guilds like Black Sword Knights and Silver Sword, a plan that proved to be quite profitable.

Aside from taking their EXP Holy Water, the leaders of the guild also take advantage of the beginners, using them to earn Gold or ordering them around for the leaders' benefits. They ultimately do not care about their members' well-being and are not above hurting them to teach them a lesson.

Hamelin apparently disbanded after Shiroe blacklisted all of its members from using their Guild Hall and freed the beginners. With no access to their funds, equipment or even their own Guild rooms after they left the building, the members of Hamelin found it virtually impossible to live within Akihabara. As a result, they were forced to leave the city and now must fend for themselves elsewhere.

Guild Hall
Like most guilds, the Hamelin guild owns a Guild Hall of its own, a special zone for its members. Though Guild Halls are originally non-combat areas, the Guild Master adjusted the Guild Hall's setting, allowing combat in order to "manage" the beginners.

With the members of Hamelin now blacklisted, they can no longer access that zone. They were able to escape by using the  'Call of Home' spell or by killing themselves and respawning in the Cathedral. However, they cannot return to their zone afterwards.

Trivia

 * The name of the guild is an obvious reference to the Pied Piper of Hamelin. According to legend, the German town of Hamelin was plagued by rats and hired a rat-catcher, the Pied Piper. Refusing to pay the rat-catcher, the Pied Piper uses his magical pipe and enchants the children of the town, taking them away.
