Octavia is a Space Mareine, a member of the Equestrium's army bio-engineered to be an unstoppable killing machine and fight off the foes of Ponykind, demonic or alien. Serving beside her battle-brethren, she swears to slay any heretic or xeno she encounters, as all Mareines aspire.

But a surprise attack mounted by the demonic followers of Vaanyl, the Discordian Goddess of Pleasure, will throw Octavia's life into a spiral of depravity and chaos.
