Sharn was given a small vial of Bloodmoon juice which she carries around with her upon a necklace to this very day. It was given to her by her Brother Logar before his disappearance years ago.
One night when Sharn was fighting monsters in a lair, she had her arm bitten off and left for dead. moments before her death, she consumed some bloodmoon which allowed her conciousness (soul/spirit) to take sanctuary within the folds. Her body was recovered and rushed to an old derelict temple in a woodland. During a bloodmoon ritual her body was revived and her conciousness allowed to return from the folds, at cost of her arm of course. Henceforth she is known as Sharn 'The One Armed'. The identty of her saviour was never revealed to the readers...
I deeply regret not saving the RP's of that incident.
