# The Thessians — Invaders from the Infinite character guide

> The Thessians in Invaders from the Infinite by John W. Campbell.

**Role:** supporting

**Also known as:** Thessians, The remaining Thessians

**First appearance:** 0002-iii-a-quarter-of-a-million-light-years

## Snapshot

Exiles and outcasts of the Warless Ones of Venone, whose Twin-ray and molecular forts make them the most feared power in known space.

## Who they are

The Thessians were banished to the prison worlds of Thett generations ago, and their revolt against Venone produced the Twin-ray that destroys relux and lux alike. They are not a single villain but a civilization forged by exile, guarded by planet-circling forts no ship can approach. Their existence reframes the war as a feud between the Warless Ones and their discarded children, and their technology defines the expedition's ceiling.
