"We used to make sure the Hyenas never came near our villages. We knew they were evil back then. We knew what would happen. But the young people these days, they've forgotten the old ways for money and material things. And they think having the Hyenas as pets are a symbol of status. Back in the old days I killed a Hyena out on the plains at night, and when it died it...changed. I haven't slept much at nights since. Especially since they've been bringing them into the city. I know they're watching me. Take this machete boy. It's special. When I die, you know what to use it for."

The Amanga Impisi is a creature from the depths of space that arrived on the world many millennia ago. It has been confused with demons and other such creatures for a long time. The Amanga's goals appear to be uncertain, as they travel not with each other but with packs of Hyenas. It is rumored they feed on the fear and madness of mortal men, and work to disrupt societies and cause massive bloodshed. They appear as vaguely hyena like in shape with hooved feet. The skin is armor plated with fleshy tendrils of some kind running down the back and sides like some sort of perverse mane. The heavily armored head is much like a hyenas skull with split nostrils and random thornlike growths. The face is blood red turning to green near the mane, with the body mostly yellow. Inhabitants in areas populated by them tend to believe the Hyena is an evil creature. Amanga speak their own language.

Madness Gaze (Su): Become permanently Insane, range 30 ft., Willpower Save DC 22 Negates (Save is Charisma Based). If the Willpower Save is failed the victim acquires some sort of permanent insanity. In normal D&D this is Insanity, as per the spell. See the Unearthed Arcana or D20 Call of Cthulhu for other examples of Insanity. The DM should pick one appropriate to the moment.

Spell Like Abilities (Sp): The Amanga can use various Spell-Like abilities as an 8th Level Caster. They get five 1st Level, three 2nd Level, two 3rd Level, and one 4th Level spells. They may choose any Divination, Enchantment or Illusion spells from the Sorcerer list. They may use the 1st and 2nd Level spells 3/day, and the 3rd and 4th Level spells 1/day.

Alternate Form (Su): At will the Amanga can appear to be a normal Hyena. This is a Mind-Affecting Glamer effect, and has no effects on stats or abilities. Creatures unaffected by Glamers are immune to this ability and see the Amanga as it is. Turning this ability on or off is a free action, but it drops automatically if the Amanga Impisi attacks.

Summon Pack (Su): Once per day the Amanga can summon a pack of 8 Hyenas. This works like the spell Summon Natures Ally V in all other respects.

Immunities (Ex): The Amanga is immune to poison, paralysis, polymorph, sleep and death affects, and stunning.

Combat: The Amanga will stalk its prey in the bush for weeks slowly destroying its mind with its spell like abilities before using its gaze to drive it over the brink. After that it and the pack tear the victim apart.

Side note: Amanga means "lie" in Zulu. Impisi is their name for the Hyena.
