Sly

Initially found in a hovel in the small village accessible after defeating Gruz Mother in the Forgotten Crossroads, slowly succumbing to The Infection. Approaching him breaks him out of his daze, after which he will return to Dirtmouth to open his shop.

When he is given the Shopkeeper's Key, more of his goods will be unlocked.

After The Knight learns all three Nail Arts, Sly will be found in his storeroom, where he reveals that he is the Great Nailsage who taught the three Nailmasters. Here he will reward The Knight with the Nailmaster's Glory Charm.

Sly being more than he seems is repeatedly foreshadowed. For instance, his very first line, "Oro, you oaf... you wield your nail... like a club..." refers to Nailmaster Oro, and he comments on the Knight’s Nail several times.

I found another of these. If you look closely, there's some nice engraving work on them.

I suspect I undercharged last time, and this is the only one left. It's gonna cost you!

You're collecting these, aren't you? Well you're in luck, I found another in my storeroom.

This is the last one though, so it's priced accordingly.

As it turns out, I do actually have one more of these shards left. Very last one!

I feel bad charging you so much for the previous shards, especially because it means I have to charge even more for this one.

I don't really like the aura about it, but it's quite rare so I'll have to charge you a high price.

You like it? It's a recent addition to my collection. Handsome thing, isn't it?

Location
Sly first appears in an abandoned house in the southeast region of the Forgotten Crossroads. After talking to him, he can next be found in Dirtmouth.

Trivia

 * According to a livestream Q&A, the development team originally planned for Sly to be a difficult boss who wielded a nail approximately the size of the other Nailmasters'.
 * Sly is the only merchant that requires the player to purchase an item to unlock the next one in the series.
 * Sly mentions a character named "Esmy" in one of his lines of dialogue. Esmy is never seen in the game nor mentioned again for unknown reasons.
 * Sly is a boss in the Godmaster expansion, but in this form, he is known as the Great Nailsage Sly. A boss who has surprisingly great skill with his Great Nail.
 * His cape is also a pinkish colour as opposed to blue.
 * Sly mentions owning a full set of Vessel Fragments although only selling two out of three; this is possibly attributed to Soul Vessels being comprised of only two Vessel Fragments at one point before being changed by release. The A Weird and Wonderful World trailer also shows Sly selling half of a Soul Vessel.
 * Sly is one of the two bugs in the game to stop The Infection from overcoming themselves, the other being Bretta.
