Lyna

"Regrets are pointless 
Lyna is a zombie elf, resurrected accidentally by Speedwell. After being approached by Speedwell and Baelyreria. She agrees to try and reverse the Deathless Age and be reunited with her lover in the Hereafter. 
In her first life, Lyna was pulled into a political struggle, conspiring to overthrow the Silverfern Royal Family. She panicked and accidentally advises her estranged husband of some sensitive information which ends up with their leader being captured and put on trial. The rest of the rebel group did not take this well and took her out and buried her deep in the woods. Her lover died soon after due to mysterious circumstances and whilst Lyna knows that they are dead, she doesn't know why or where they are.
