Modrons are beings of absolute law that adhere to a
·. hive-like hierarchy. They inhabit the plane of Mechanus
and tend its eternally revolving gears, their existence a
clockwork routine of perfect order.
Absolute Law and Order. Under the direction
of their leader, Primus, modrons increase order in
the multiverse in accordance with laws beyond the
comprehension of·mortal minds. Their own minds
are networked in a hierarchal pyramid, in which
each modron receives commands from superiors and
delegates orders to underlings. A mod ron carries out
commands with total obedience, utmost efficiency, and
an absence of morality or ego.
Modrons have no sense of self beyond what is
necessary to fulfill their duties. They exist as a unifie d
collective, divided by ranks, yet they always refer to
themselves collectively. To a modron, there is no "I," but
only "we" or "us."
Absolute Hierarchy. Modrons communicate only
with their own rank and the ranks immediately above
and below them. Modrons more than one rank away are
either too advanced or too simple to understand.
Cogs of the Great Machine. If a modron is destroyed,
its remains disintegrate. A replacement from the next
lowest rank then transforms in a flash of light, gaining
the physical form of its new rank. The promoted mod ron
is replaced by one of its underlings in the same manner,
all t~e way to the lowest levels of the hierarchy. There, a
new mod ron is created by Primus, with a steady stream
of monodrones leaving the Great Modron Cathedral on
Mechanus as a result.
The Great Modron March. When the gears of
Mechanus complete seventeen cycles once every 289
years, Primus sends a vast army of modrons across the
Outer Planes, ostensibly on a reconnaissance mission.
The march is long and dangerous, and only a small
number of modrons returns to Mechanus.
MONODRONE
A monodrone can perform one simple task at a time and
can relay a single message of up to forty-eight words.
DUODRONE
The blocky duodrones supervise units of monodrones
and can perform up to two tasks at a time.
TRIDRONE
Tridrones are shaped like inverted pyramids. They lead
lesser modrons in battle.
UADRONE
Astute combatants, quadrones serve as artillery and
field officers in the regiments of modron armies.
PENTADRONE
Pentadrones oversee Mechanus's worker populace and
call improvise in response to new situations.
A mod ron unit sometimes becomes defective, either through
natural decay or exposure to chaotic forces. Rogue modrons
don't act in accordance with Primus's wishes and directives,
breaking laws, disobeying orders, and even engaging in
violence. Other modrons hunt down such rogues.
A rogue mod ron loses the Axiomatic Mind trait and can
have any alignment other than lawful neutral. Otherwise, it
has the same statistics as a regular mod ron of its rank.
