Impulse the settlement, was build upon a series of underground networks; a move made to ease the construction, of the facilities which would later be known as the I.R.D.
Around just 10% of this space is actually inhabited on a daily bases though-
What’s to be found in the other 90 are; dizzying series of pipes, far-gone structures of the past, wires, and a source of lighting… if you’re lucky.
It is quite possible to get lost, within these seemingly endless voids of darkness, as such not many are permitted entrance. The task of fixing/monitoring the network of pipes is usually left to high ranking members of the I.R.D.
In the above, Mik can be seen preforming (filling-in for a peer) a weekly check, on parts of the network deemed as “high usage”.
