NPC's who sell charms and items

[TonkatsuRamen]

Can someone list me all the NPC's with the area they're in that sell stuff?
I have the feeling I might have missed one or two...

[Kein Zantezuken]

Sly
The Witch
Leg Eater
Iselda

I know the one in Dirthmouth, The map seller (iselda?), the witch in crossroads and leg eater is the small bug right?

[Kein Zantezuken]

Sly is a small bug, you rescue him in crossroads

[TonkatsuRamen]

then who is the leg eater ?

[Hakanasaganas]

Leg Eater is the vendor of Fragile Charms, he's located at Fungal Wastes. He will sell his items cheaper when you have the Defender's Crest on.

Then I got all of them. But I'm swimming in GEO .... no idea how to spend it
