Location from Arcane by Riot Games
Once the Blessed Isles of arcane knowledge and natural beauty, now a cursed archipelago shrouded in the Black Mist that devours souls and spawns undead horrors across Runeterra.
The Shadow Isles are what happens when love becomes obsession and grief becomes cataclysm. When the Ruined King Viego shattered the Waters of Life to resurrect his queen, the resulting Ruination consumed everything — the scholars, the gardens, the very concept of peace. Now death is not an end here but a beginning. Spirits wander in endless torment, reliving their final moments. The Black Mist periodically surges outward, reaching distant shores to harvest more souls. Thresh delights in collecting and tormenting the damned, while Senna and Lucian fight to contain the spreading corruption. The islands remember what they were, and that memory is the cruelest haunting of all.
Twisted black trees claw at a perpetually overcast sky, their bark weeping luminescent sap. Crumbling ruins of once-magnificent architecture jut from corrupted earth, while the Black Mist rolls between them like a living fog, shapes of screaming faces briefly visible in its depths.
