SHIGEKO'S DOSSIER: I wish I could take credit for employing this endlessly useful eta, but I'm afraid that honor goes to my predecessor, Isawa Choyo.
Eyebrows is an herbalist and surgeon for the Leatherworkers, and also has some status within their fire-fighting league (which also serves as a de facto police force). When she wrote her dossier for me, Choyo stressed Eyebrows' proficiency at a skill he calls "dead reading." This is nothing less than the ability to gain information from observing a dead body.
While this may sound like black magic, I assure you it is completely mundane. It is simply a matter of keen eyes and knowledge of certain signs - much as a skilled hunter knows how find tracks where game has passed. It seems that among the eta, the morticians are also the community healers. (It's appalling to think of one individual serving the dead and living alike - but that's why they're eta, after all.) While preparing the dead for burial, these healers have learned to see signs that indicate the cause of death. Eyebrows is so skilled that he can look at a man killed by a sword blow and say if he died quickly (from shock) or slowly (by bleeding to death).
Dead reading has proven invaluable on many occasions. In fact, Eyebrows is not limited to reading the dead; by looking at an injury, he can tell what sort of weapon inflicted it, how long ago, and from which direction the attack originated.
Although working with an eta may seem unpleasant, I assure you that Eyebrows knows his place and is respectful at all times.
