Not Redin. Not Marsh. Not Vasher. Not Rock. Not Gaz. Not Maya. Not Spook. This character makes things sharp. This character keeps an eye out, after a fashion. This character is disqualified for an elevated position. This character styles out some espionage.

Nice one! This character makes things sharp.

Alright, I had to do some searching. The word "gaunt" appears only twice in Elantris. Ketol, the chap who meets Sarene when she first arrives. I must commend the depths of obscurity you plumbed. I forgot he even existed.

Roial? He's spindly, but he's not obscure...

Ahan, the cad.

Vo.

Go for it, @Ishar, I'm going to be busy for the next couple of days.

@animaliaNot Mennis. @AceBassMan Not the Marksman. Not Edwarn. Not Lift. Not Tonk Fah. Not Kaladin. Not Vasher. Not Vin. Not Kelsier. Not Chesterton. I am overjoyed to have got to five clues with this character, so here are some more details! Tell me which one gives it away... This character employs violence when committing a crime. They hit someone when stealing something. This character takes performance-enhancing substances. They are an Allomancer... and a performer. This character makes their own mode of transport. They make a vessel out of unconventional materials, to navigate a strange place. This character is generous with other people's money. They give away a very valuable coin that definitely doesn't belong to them. This character shelters one in need. They provide a moment of peace to someone going through hell.

Looked it up on my Kindle - it was "Rothan". Nice one! This character employs violence when committing a crime.

Leshwi's main dude, the military counterpart to Venli. He goes with them to Urithiru. I've got the name "Roshan" in my head but I know that's not right.

Dalinar. Just want to throw some appreciation @AceBassMan's way for such a wide variety of guesses.
