It's a loose guild with one leader and everyone else organizing themselves into teams based on the contracts they decide to take. There are a few teams which are common enough to earn their own names, but most are fluid in their partnerships. Adhi also sometimes assigns teams for missions if he believes their particular skill sets are suited to the mission, usually a particularly sensitive one.
To make a bunch of money and kill a bunch of monsters.
Their guild hall is large and built in the style of a hunting lodge, with various monster parts mounted on the walls as trophies. There is also a in-house bar and dining area for Singers to take their ease when looking for contracts or waiting for new ones.
The guild was founded two years ago when Adhi left his previous and very lucrative profession to go out on his own and do something different. They quickly became a powerhouse in the Hunter's guild world, partially aided by Adhi's mysteriously acquired wealth, and partly aided by his charismatic approach to recruitment.
