Developed by the Central Timespace Bureau in 2923, SmogPurge is a software for uplinking alternate futures concerning the Great Smog. Pieces of the source code were lost in hyperspace during multi-dimensional distribution and ended up centuries earlier.

The Central Timespace Bureau created the first space-time messenger in 2917 A.D.

The moment it's turned on, a repeated message flooded the system:
"They triggered the The Great Smog."

Soon we understand we live in a reality where the Great Smog was delayed for unknown reasons.

Under the collective effort of different realities, the bureau created the "SmogPurge" software, to uplink alternate futures as a means to understand the Great Smog.

Pieces of source code were lost in hyperspace transmission, and ended up centuries earlier where bio-engineered dragons and self-conscious military robots were still distant dreams.
