Collegia Titanica

The Collegia Titanica are the Titan Legions produced by the Adeptus Mechanicus. These machines are often called God-Machines most likley because their huge size, warlords standing over 100 meters tall and with the destructive power to level citys. One of the most famous legions is the Legio Tempustus. Their orgins date back to even before the great crusade. They stood with the emporer and have been fighting for over 10 thousand years for the imperium of man. These machines are the most powerful land based unit the imperium has. Their are four distinct classes of Titans:

The warhound is the smallest titan and they are usually scouts and ambushers.

Reavers are usualy support units for the Warlords.

Warlords are usually the bigest and most destructive machines in a Legio.

Sometimes a Legio Might have an Imperator class Titan and they are basiclly super Warlords.

In one case I have Heard of an Emporer Class Titan which is about equal to Four Warlords or Two Imperator Class titans.
