For Want of a Rainboom

In a world where Rainbow Dash didn't perform the first sonic rainboom, three familiar faces will become interconnected under very different circumstances.

For want of a rainboom, six cutie marks are lost. For want of six cutie marks, six lives are changed. Familiar faces appear under very different circumstances. A Manehattan banker. A Canterlot bureaucrat. A Cloudsdale mail carrier. Through the cutthroat world of finance, their lives will become interconnected.
