Man Eater

Monsters are creatures of nightmares, and there many such creatures, and each country got at least once. For Kreek, it's the Man Eaters. The fear of being eaten alive by a servant of the god you follow and worship is the worst for them. Not only do you die, eaten alive and in front of your opponents, but it's a sign that you have greatly disappointed the one that has been essential for your people's survival through many generations. No fates are worse.
A Man Eater only shows when a follower of Nadgaj shows fear in combat and only stays for as long as it's target, the one who dared show fear, is alive. Once it has done it's duty, eaten the target alive in front of the target's opponent of the fight it interrupted, it will go back to it's master and await further orders.
It's said that when Kreek faced all it's enemies at once, Nadgaj arrived with an army of Man Eaters in defense of her people. If another great threat was to threaten the survival of Kreek, Nadgaj would come down once more with her army of Man Eaters.
