A wagon lays overturned on the forest road, bodies savaged by tooth and claw lay strewn about it, their weapons clean of blood, seemingly unused.
A lone man runs from an unseen threat, deeper into the forest, away from the grisly scene in the road. He stumbles, his foot having caught on a root. He lands hard, his lungs feel like lead. Panting, he comes to his knees. Two eyes of emerald light meet his, a low growl emanates from the beast, and his death is swift.
The spirit of a creature trapped in amber cannot escape to it’s afterlife / next incarnation / whatever.
Such trapped spirits can be contacted by those who know the right rituals and magical power derived from them – typically the power to control one individual of that species.
Can by quite powerful if the creature is a colony insect (ant, bee, wasp, etc) – simply control the queen and you command the whole colony.
