Kobolds.
I am the Scaled Arcanist, and together with an associate, I offer you freedom. I offer you wealth. I offer you oppurtunity. Together we in this darkness will grow strong. Together we will gather our numbers, and fight those who chase us.
Leave word here, or hidden, beneath the rock to the left of the gate in the old goblin tunnel, and I will find you.
*beneath on the same poster is a drawing depicting a single, vaguely sketched kobold in robes, standing in the shadows past a torchlight with his arms stretched out invitingly. Behind him is someone of a humans length, covered with metal armour, but his head concealed in the shadows. A mass of reptilians scurry across the lighted area towards them.*
