Seeking translation for Lone Wolf in Sindarin for pop-up tattoo event.

Thank you for allowing me to join this community! My life partner bought me A Gateway to Sindarin for Christmas and I have not been able to read it because we have been in the process of moving to a new home. I am hoping that someone here might help me with a translation of the phrase lone wolf. I would like for it to be as accurate as possible in the most beautiful script. I have looked at Tecendil, but i did not take into account any other translations before entering solely the words lone wolf into the translator. Any help would be appreciated as this tattoo would not only mean a lot to me personally,, but it would be a means to commemorate the event tomorrow because it is one of my best friends event. Thank you so much!
