Doctor Who Fear of the Dark by Trevor Baxendale

This text, which is an excerpt from a book titled "Doctor Who: Fear of the Dark," follows the adventures of the Doctor and his companions, Tegan and Nyssa, as they encounter a commercial mining operation on a desolate moon, Akoshemon. The Doctor investigates a subterranean laboratory and an ancient, evil entity known as the Dark that has corrupted the planet and is tied to a blood-draining creature, the Bloodhunter. A key conflict unfolds between the Doctor's group, the miners led by Jyl Stoker and her explosive expert Bunny Cheung, and a Consortium officer named Captain Lawrence and his ruthless 2IC, Cadwell, particularly concerning the planet's valuable mineral, lexium, and the growing danger from the Dark. The narrative details terrifying encounters and multiple deaths as the Dark attempts to escape the moon and spread its influence through the Doctor's time machine, culminating in a violent confrontation where the entity is temporarily defeated and pushed back into the void.
