H

Helotrix

A swampy industrialized planet whose populace, called the Helots, were quickly annexed by the Federation by means of the pacification drug Pylene-50. The drug was administered via a "medical laser" that appeared function like a hand-held beam weapon. Some of the un-pacified Helots formed a resistance group lead by a man named Hunda who helps Tarrant and Dayna track down Forbus, a chemist who was forced by Servalan to create the drug along with the antidote to neutralise it.

Herom

Planet mentioned to have suffered climate control problems after the sabotage of Star One.

Hirrial

Star system represented in Avon's alliance of local warlords by Lod.

Horizon

Federation code name for the planet Silmareno, a jungle planet at the edge of the galaxy that was under Federation control. The planet was protected by an intense magnetic field that could only be traversed by ships equipped with special magnetic baffling. Liberator barely survived entering orbit with the force wall activated. The natives of Horizon were a pre-industrial civilization whom the Federation used as slaves to mine the planet's rich resources. Blake was able to convince their leader that the Federation was exploiting his people.

"Host Planet"

An unidentified world believed by Orac to be a single living entity in itself that feeds on its surface life-forms. Blake goes to this planet to "think" after the death of Gan, and meets a curious native creature named Zil. Zil warns Blake that the Host will find him — that being the very ground itself which tries to swallow him up.
