Epilogue

Outnumbered, outclassed, leaderless, out of position and with no way of reaching Scarlett Silverlight in a timely manner, the remaining dungans and Wolfpack decide to retreat. (I didn't want to cut it short just to be rid of it, I genuinely think they had no more chance of achieving their objective, and just reaching the imperials would've taken several turns or simply failed if they just chose to retreat towards the objective).

Despite heavy losses, Tatters and Lyra are able to escort Scarlett to safety. An important victory for the Empire!
