From publisher blurb:
Welcome to Mechanika.
A world where flux, the very life energy of all things, has been harnessed by man and monster alike. A world that has been forced to adapt to how its native and alien residents bend and twist this powerful energy to form strange and terrible magics and artefacts.
This is London in the Celtic empire. The year is 1897, and the great dominions of the world are at the brink of war.
It has been almost 1900 years since the Fae Trods closed, and 1900 years since the supposed defeat of the Great and Terrible old ones. The world has been forever changed by invaders both benign and malevolent, hailing from the deepest parts of the dark void. Bizaare new guests with amazing and awful powers. and no means with which to escape this prison we call Earth.
Your group is one of many groups calling themselves the Nouveau, or new thinkers. People who reject and refuse the stingy, pompous victorian world, and instead reach for something different using your unique gifts to alter the world.
Your group has pooled your individual talents and resources and founded the Icarus Detective Agency. Together you investigate the alien threats that the police ignore, or that they lack the power to fight.
