Pyroclast

"You must face the truth squarely and without flinching from duty. Our enemies are mortal no longer. Mercy for such as they is a chimera, self-deception is its only ally. Dedicate this weapon, given unto your hand at the behest of the Emperor, to their destruction. Regard its function as your only duty: you live only to bring cleansing fire. Take up your rod and staff, your armor and psycannon, and go forth."
–Lectures to the Ordo, Inquisitor-Historical Galbus Heer
What others of the Inquisition do through stealth
and guile, the Pyroclast does through
the cleansing flame of righteousness.
Originally created as a group by Inquisitor Malachai Heritor in 643.M40, the Pyroclasts
were intended to be sent in when the only hope
of ending a xenos infestation was through the
application of holy fire. The success of the Ordo
Xenos Pyroclast squads led the Ordo Malleus to
apply the same principles to Daemon hunting.
Original records of which Inquisitor first
attempted this have been lost to time,
but the results cannot be overstated. The
first recorded use of Pyroclasts happened
on the Agri-world of Dreah. Grain that
had been tainted by Chaos was planted in
the fields of many unsuspecting farmers.
During the harvest, the stalks of this grain
poisoned the tithe of Dreah. Learning
of this tragedy, Inquisitor Helden Karros
equipped three full regiments of Imperial
Guard to combat this menace. Within a single
month, the entire crop of questionable grain had
been incinerated under the relentless onslaught of
the flamers of the Pyroclasts. To be sure that
the taint had been rooted out sufficiently,
Inquisitor Karros ordered a cleansing of
all vegetation with a thousand kilometer
radius of the original planting site.
With the Cleansing of Dreah
complete, the Calixian Ordo Malleus
created a training bastion on the Shrine
World of Reshia for Inquisitorial agents
specializing in the use of Incinerators. Within this
bastion recruits are schooled in the nature of flame
and the cleansing power that it holds. Other Inquisitors
are known to maintain elite groups of such Guardsmen,
either privately trained or sent to Reshia for instruction.
==Alternate Career Rank==
Pyroclasts are mostly recruited from experienced Guardsmen.
Those chosen must already have an instinctive understanding
of the nature of fire. During Pyroclast training, this grows
into an almost religious love and faith. Once selected, the
majority of Pyroclasts are sent to Reshia for a period of six
months for indoctrination and training, and then returned
to their Inquisitor with the skills necessary to illuminate the
dark shadows of corruption with the light of the Incinerator.
Required Career: Guardsman
