The fourth day was nearing its end as the sun began to set.
According to the original plan, Secret was supposed to attack the frozen river, where Margo's men had set up camp to prevent them from obtaining the flag. At the same time, Margo would have taken over the Sirius faction with the help of Rigel's forces.
The Rigel faction members inside Sirius' castle were supposed to strike at sunset, destroying the Sirius faction as much as possible, before withdrawing to join Secret and her forces, who would then handle Margo.
The plan was supposed to result in a complete victory for the Mira faction, with almost no losses. Afterward, the best from both the Rigel and Sirius factions would be enslaved, while the rest would be discarded mercilessly...
This was Mustang's plan, but Cassian had shattered it to such a degree that completing it was now impossible.
