Aliase's Orb of Oubliette

To the untrained eye a simple glass orb misted with a suspicious obsidian liquid substance swirling around inside.

Choose a target to curse with this object within 60ft, while cursed until the target has died and 100 years have passed they will be unable to retrieve the imprisoned subjects magical or otherwise. Even if the Arch Hag, Aliase, dies the prison shall remain intact. Remove curse does not remove this curse, the only way to free the captives before the target dies is to destroy the pocket dimension itself.

To activate this orb smash it on the ground around any creature and any creature within a 10 foot radius must make an 18 Dexterity Saving Throw or immediately be teleported to Aliase's Pocket Dimension of Imprisonment. Aliase can stipulate whether the creature she gives the orb to can automatically succeed or fail.

Any creature's within the dimension are unconscious and immune to all damage. If and when released, the creature(s) inside the gem will return with the effects having a long rest.

Once the orb has been activated, Aliase is aware whether creature's have been captured or not.
