Collectors
These warlocks have strange needle-like fingers which they insert into people's brains and gain information quickly. After a collector's attack, the person will lose at least part his memory and become catatonic.
Spells & Potions
Spell to Hear Secret Thoughts:
Light a blue candle and chant:
As flame lights shadow and truth ends fear
Open locked thoughts to my willing ear.
May the smoke from this candle into everywhere creep
Bringing innermost voices to my mind in speech.
