Twin?

Lorn blinked when she saw a twin of herself sitting in a curled up state in a tight cage that dangled from the ceiling by a chain. The girl regarded Lorn with interest. “Luzzst, you seem more yourself, less feeble,” Lorn’s twin observed. Lorn shook her head and beckoned for her twin to be silent. “Don’t try to cast a spell again. The collar will prevent it...”

Lorn frowned in sudden concern. The collar had not prevented her from entering this form but... she started to will herself back to the amulet when her mind grew cloudy and her will grew weak and uncertain. She stopped, realising that the magic was being perverted by the collar and used to enfeeble her. Had she continued she would have been turned into a vegetable. As it was... “Oh no...” she was trapped in this body and couldn’t cast any spells. She looked across at the tiefling and shuddered at her own fate.

“She speaks. Interesting,” Lorn’s twin said. Lorn regarded her twin then blinked as the figure changed subtly, becoming featureless but still female.

A doppelgänger! Bargle did like interesting slaves it seemed.
