A plane of magical horrors called Duskmourn is dropping into Magic: The Gathering as the final 2024 Standard-legal set.
As with most MTG sets, the name of the plane is the same name assigned to the set. Duskmourn the plane is home to the imprisoned Valgavoth demonic entity, according to Wizards of the Coast. Valgavoth controls the house he’s imprisoned in and with the additions of newly formed Omenpaths across the Multiverse, the demon is luring in new victims to satisfy his hunger. The house Valgavoth is imprisoned in is essentially alive, creating spaces like the Boilerbilges and Hauntwoods.
