Summary
Ophelia Phamrsolone. One of the greatest talents of the Clock Tower' Department of Spiritual Evocation; the modern-day Valkyrie with a Jewel-rank Mystic Eye.
The typical world of Fate/Grand Order is not kind to her. Tasked with maintaining the tenuous balancing act of the Scandinavian Lostbelt - appeasing its King and keeping its apocalypse at bay for its potential use to the Crypter cause; forced at odds with one she wished dearly to call friend.
Ophelia had tragically little choice or agency in her life. She chose to become humanity's enemy, and she chose to sacrifice herself to help stop Ragnarök. But her path was set before the Incineration, and arguably during the Revision.
How might things change, if she had more branches in that path… if she chose to step onto another?

Summary
The year: 60 AD. Shortly after Boudica's crushed rebellion and the death of Emperor Nero's mother, during what should be a time of peace, the glorious Roman Empire finds itself under attack by a rival claiming to be the true Rome. Their soldiers are even more dedicated, and each of their 'emperors' can match legions.
This 'United Roman Empire' has already claimed half of the Roman Empire's territories. With even the Red Rose unable to stop their advance, their claim on the capital is but a matter of time.
This is the site of the second Singularity of the Grand Order. The scope might be even larger than the two before it, but with their training, experience, new teammates and new allies (and, of course, foreknowledge), Team R should hopefully have this well in hand.
For the glory of the Seven Hills - onward!
What else you can expect in this work (clicky):

21 Oct 2015
Tags
Summary
This is a live example how to make invisible text that can only be seen by highlighting the text. Tutorial is included in text, and you can always leave comments about questions you may have.
MOBILE USERS: Sadly, this probably won't work for you, since highlighting in a mobile browser is different than web. I've tried correcting this, but have yet to find a solution.
