(Writhing) Possessed Lady Sophie

Lore
No one was able to ascertain the nature of whatever haunted Sophie, but its lethal intent was obvious. It had transformed her graceful, slender legs into frightening appendages that slay without remorse. An entire army unit was needed to capture her, but they soon found she could not be killed. With no other option, she was banished to Hecate's prison, never to return.
