Dark Star and the Winter Guard
Reena served with the Winter Guard for sometime and admitted that she was afraid that she was not living up to Laynia’s memory. She also got strange vibes of the medallion that had originally belonged to Laynia Petrovna, the original Darkstar. Sometimes seeing things that where apparently not really there, such as the present of the first Darkstar. She however assisted the Winter Guard on a few occasions. Once she assisted her team in helping to defeat a number of Dire Wraiths, but was ultimately killed and transformed into one herself. The original Darkstar used this opportunity and the connection she had with her medallion to resurrect herself in Reena’s body.
