Scenes from a shared world

Familiar places, new company

From a flight above the grounds to a quiet corner of the castle, captured in-game by players.

Stay a little longer

Life at school

A place to belong

A world worth sharing

The castle was never meant to be empty

Hogwarts Legacy gave us a magical world in breathtaking detail: the Great Hall, the Undercroft, the Forbidden Forest, the shifting staircases. ArcaneMP fills it with people.

Familiar faces in the corridors. Wands raised side by side. Friends waiting in the common room. Your character, robes and spells come with you into one shared world.

From a quiet evening by the fire to a flight across the Highlands, the best stories are the ones you make together.

From the changelog

Latest testing release ·

Version 1.12.0

HogwartsMP becomes ArcaneMP, with arcanemp:// join links, wild and enemy animal forms, and server-placed lights and colliders.

  • The mod is now called ArcaneMP. Join links use arcanemp://, and servers keep their HogwartsMP masterlist identity, so existing listings carry on. Script types still publish as @hogwartsmp/types.
  • Animal forms now include the game’s wild animals (rat, hare, deer and owl) and its enemies (acromantula, troll and wolf), which move with their own creature abilities.
  • Servers can place point and spot lights, invisible collider shells that stop characters, spells or both, and mirror colliders that deflect wand bolts and put out Incendio.
