The hand of Nus

The hand of Nus is a guild of assassins who take contracts from anyone who leaves a black rose in their windowsill for 3 days. After the 3 days the guild will send an agent to work out the contract. The guild names a price and the client pays half before the job then the other half after.

The guild is led by a being known as Vast but no one has ever seen them, they merely approve or reject the contracts. It is unknown how they are contacted by the guild.
