Thinking the golden collar with the runes had the magical power to kill her peoples oppressor, Princess Dorin donned the arcane collar in Lord Zargoths presence.

The magic rippled accross her body shifting bones and muscle. At last she would crush her people oppressor with her own hands. It was then that she noticed her body wasn't growing larger, it was shrinking downward, becoming weaker. Months of physical training by her barbarian allies wasted within moments.

Her eyes adjusted to the darkness with unnatural ease allowing her to see the form that stood before her.
The dark lord was handsome... powerful...
She relised with a start the collar was affecting her mind far faster than she could react to it. Soon she was gone, replaced with a new slave.

Zargoth enjoyed these games, allowing a resistance group to steal a magical item from him with the incorrect information. Generally having the results blow up in their faces. Princess Dorin was always a thorn in his side, now as a bunny girl, she might become a pain somewhere else.
