A certain seer warned Caesar to be on his guard against a great peril on the day of the month of March which the Romans call the Ides; 6 and when the day had come and Caesar was on his way to the senate-house, he greeted the seer with a jest and said: 'Well, the Ides of March are come,' and the seer said to him softly: 'Ay, they are come, but they are not gone."
~Plutarch, Parallel Lives

What if Gaius Julius Caesar had heeded that warning and the other signs leading up to the Ides and survived that day in March of 44 BC?

This is the premise behind Caesar Ascending-Invasion of Parthia, which is the predecessor to Caesar Triumphant, an alternate history where Caesar, after his planned invasion of Parthia, continues marching east. Whereas Caesar Triumphant covers Caesar's invasion of the Isle of Wa, now known as Japan, Caesar Ascending is set in 44 BC and tells the story of his planned invasion of Parthia, and includes the characters of the internationally bestselling Marching With Caesar series, featuring Titus Pullus.

Determined not to repeat the mistakes made by Caesar's friend and fellow Triumvir Marcus Licinius Crassus, the Dictator has trained his Legions in tactics specifically designed to thwart the famed Parthian cataphracts and horse archers, but as Caesar and his army learns, the Parthians have been working on their own surprises, all in an attempt to destroy another Roman army and send a message to Rome that they are not the only world power.
