There are several NPCs in Winterspring, in Everlook.
These NPCs are all in the same building (the bank) and each one is for a specific type of weapon, and they also have quests for plans for those types of weapons too.
However, from what I've seen, most, if not all, of the quests require various higher-level instances, for example, the Axesmith quest has you going to BRD if I recall correctly.
