Sly

"All's fair in a world made of Geo."

- Sly

Sly is a Merchant in Hollow Knight. He sells many wares at his shop in Dirtmouth for Geo but drives a hard bargain. Sly also appears as a boss as the Great Nailsage Sly.

Lore
Sly used to be the Great Nailsage. During his previous occupation, he trained some disciples in the Nail Arts: Oro, Mato, and Sheo. All three can be found in the game.

After the kingdom's fall and the separation of his Nailmaster pupils, Sly abandoned his occupation as Nailsage. He turned to a simple life of a merchant, finding and selling wares from his shop in Dirtmouth. He did not, however, forget his mastery of the nail, and keeps his greatnail in the basement of his shop.

At some point, a dream led him to close his shop and wander off in the caverns below Dirtmouth. He also lost his Shopkeeper's Key which ended up in a room in Crystal Peak.

Hollow Knight
Sly can be found in a hovel in the abandoned village at the bottom of the Forgotten Crossroads, past the Gruz Mother. The shopkeeper has been slowly succumbing to the Infection, but approaching him breaks him out of his daze, saving him. After which, Sly returns to Dirtmouth to open his shop, without any recollection of how he fell into that predicament.

Back in Dirtmouth, Sly sells various wares: from Charms to adventuring gears, even Mask Shard and Vessel Fragments. His backstock, however, remains locked until he is returned his Shopkeeper's Key, lost in the Crystal Peak.

Sly notes when the Knight has honed their Nail, but also when they start learning Nail Arts. After they learnt all three Nail Arts from the Nailmasters, Sly will be found in his basement, where he reveals his former profession as Nailsage. Here he will acknowledge the Knight as Nailmaster, and reward them with the Nailmaster's Glory Charm.

As part of the Godseeker's ritual, Sly's mind is summoned to  Godhome. There he takes his original mantle of Great Nailsage and fights the Knight, his thoughts focused solely on his days past. Upon defeat, Sly bows respectfully to the Knight. He is fought at the peak of the Pantheon of the Sage and later within the Pantheon of Hallownest.

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.

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

 * 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.
 * 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 mentions a character named "Esmy" in one of his lines of dialogue. This character is never seen in the game nor mentioned again. In a Reddit AMA it is stated that Esmy is someone that still lingers in Sly's dreams.
 * As the Great Nailsage, Sly's cape is a pinkish colour as opposed to blue.
 * Sly mentions owning a full set of Vessel Fragments, although he only sells 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.
