Olympius became the Selket. Rosalina never returned.
The plan was for Rosalina to return to the Olympius after she was fully healed and Amelia-Grace was ready to move out of the medical treatment rooms. The only issue was by the time Rosalina was ready, the Olympius was known by a different name. The Selket. The Selket was no longer in command of Captain James Riley, but instead was commanded by Colonel Mark Webb.
Rosalina had never met this Colonel before so keeping in touch with James was very difficult. The communication between the two was of secret. Captain James Riley, came the second in command of the vessel with Colonel Mark Webb would command it as well as the 4th Black Lance Battlegroup. For Rosalina, her path was now at a halt, she had to think of something else to do. She was unable to just go into Omicron Mu and call for the Grand Admiral Golanski to authorize her to rejoin the crew of what was the Olympius.
What Rosalina done, was returned back to the Rheinland sector with Amelia-Grace to try find a safe haven. This was because it would be alot easier to identify that Rosalina was not just human, but infected. Which made things more challenging due to her having a daughter. Amelia-Grace had no father, her father was unknown. Her mum was Rosalina Romanov who was being hunted by The Core, Auxesian's, and even more organisations. The reason was not one hundred percent clear.
Although Rosalina Romanov escaped from the 5th Fleet, Liberty Navy several times, she fears that Colonel Webb, was and has been instructed to find and assassinate Romanov because of this. When Rosalina escaped from the prison, one of the 5th Admiral's where shot and killed on her escape.
So Rosalina's main goal right now is to find some where safe for her daughter to grow up and live a happy life. To do this she needs to stay under the radar. The priority for Rosalina now was to stay out of the Omicron's and not be found or spotted by anyone or anything that she does not know.
The only people Rosalina would trust was Captain James Riley and Jared Nomak. Not having the ability to contact Captain Riley, her only option was to get in contact to Jared Nomak for protection.
But, the last Rosalina heard, was Nomak is not around and the person within the Commune she has to go to was Bassam Hussaini. Communications where made where Rosalina found that out, but comms where cut, Rosalina at this point is out there on her own with Amelia-Grace.
Her current position is unknown, but it is some where in the Rheinland sector. Trying to establish trusted allies, friendships and a safe haven for her and her daughter.
