You am new at Sanctuary. They know you are powerful, but nothing more. Will, Helen, Henry and Nikola are there to welcome me. They feel a shift in the air. Just as Helen was revered by The gentle gift that she got from the source blood (dark Heyoka), as soon as you walked in, they got the same feeling from you. They revered you too. You had a gentle gift as well and Helen didn't know what to do with that.
