You were Captain Om'en a dragon overlord with the ability to shift between your natural four footed feral form and a more bibedal humanoid and smaller form.
Back in 1850 you had approached the Coalition
with a revolutionary idea.The human world was falling apart and the forecasters had predicted the species would go extinct before they built their first
hyper space drive.
It was going to be a little difficult to be a Overlord in a world where the apes had
exterminated each another.
Since you had known there was a old obsolete submerible hyper space drive capable submarine
due for demolition you had pitched the Coalition to disguise the vessel as a Victorian era submarine called the Nautilus,man its upper decks with mechanical humans and
use it to guide the human apes towards
a Overlord friendly future.
Your slightly batty cousin
Mi'Na had built a mechanical human she'd named Captain Nemo
and you and the mechanical human had convinced skeptical Coalition members
to go along with your plan to aid humanity.
