Each city and hunting ground has its own set of NPCs to interact with. Common ones you'll rely on constantly include:

Job NPCs — for registering as a Trader, Hunter, or Thief and managing job-related goods.

Blacksmiths — for repairing and upgrading equipment.

Alchemists — for handling elixir-based item enhancement.

The Equipment Exchange NPC — for trading equipment into a different item of the same category.

Storage keepers — for accessing your account/character storage.

Skill and stat trainers — for resetting or adjusting your build where the server allows it.

Traveling between cities and hunting grounds along the road is a core part of the game's rhythm, with each stop offering its own mix of monsters, quests, and services.
