The state of having less than an optimum level of selyn. A Sime after Turnover is consider low field, as is a Gen who has given Transfer or has donated. A Gen who has survives a Kill would be low field also.

Judging who is high and who is low field in a room is one of those issues that prevents Gens from mastering Simelan because Gens can't zlin and thus can guess (for some experienced Companions or endowed Gens very accurately, but never reliably) who is high and who is low field relative to others in a room, but they can't always get it right.
