Three new event NPCs can be found at West Park. Each serves a different purpose, so it helps to speak to them in this order:
Bawx

Use this NPC to teleport to the Cathedral, the central hub for Halloween content, enemies, and Hollow’s raid arena.
The Sigma of Halloween

This is the event exchange vendor. Speak to him to convert Candy into uE. uE is used to roll for returning Halloween skins and kill effects.
Distinguished Wolf

Interact with this NPC to begin the Shinigami Questline. This quest has returned for a limited time and now includes mastery progression for Shinigami.
