Modron ("mother") is a figure in Welsh tradition, known as the mother of the hero Mabon ap Modron. Both characters may have derived from earlier divine figures, in her case the Gaulish goddess Matrona. She may have been a prototype for Morgan le Fay from the Arthurian legend.
Modron largely features in the Welsh tradition as a supernatural mother figure. She likely derives from the Celtic goddess Matrona, known to have been worshiped in Gaul. Similarly, Modron's son, Mabon ("youth"), appears to derive from the youth god Maponos. Both Matrona and Maponos were worshiped in the area around Hadrian's Wall, which may account for the prominence of Modron and Mabon in literature connected to the Brittonic Hen Ogledd (Old North) of Britain. Certain elements of Modron's story – specifically that her son Mabon was stolen from her in the night as a baby – suggest a connection with Rhiannon in the First Branch of the Mabinogi, whose son Pryderi was similarly stolen; William John Gruffydd suggested that Modron and Rhiannon were the same in origin.John T. Koch suggests that Saint Madrun, a daughter of Vortimer, may also be connected, based on the similarity of the names and some elements of their stories. Other scholars believe the names Modron and Madrun are likely to be etymologically distinct; Madrun comes from the Vulgar Latin name Matrōna (also a common noun matrōna "matron", from Classical Latin mātrōna), while Modron is from the Gallo-Brittonic theonym *Mātronā "Mother (goddess)".
In the fictional multiverse of the Dungeons & Dragons fantasy role-playing game, Modrons are creatures native to the outer plane of Mechanus. Modrons resemble geometric shapes with humanoid limbs and represent a living, physical manifestation of law without regard to good or evil. They follow a strict hierarchy, with each rank reporting to the rank directly above it, and issuing commands to the ones ranking beneath it. For example, a quadrone modron will report to a pentadrone, and command several tridrones.
Modrons were created by Francois Marcela-Froideval, working from suggestions by Gary Gygax. They first appeared in 1983, in the AD&D 1st edition Monster Manual II, which introduced the base modrons (including the monodrone, the duodrone, the tridrone, the quadrone, and the pentadrone), the hierarch modrons (including the decaton, the nonaton, the octon, the septon, the hexton, the quinton, the quarton, the tertian, and the secundus), and Primus (The One and the Prime).
Just go to sleep
Talk is cheap
The price is steep
For the secrets we don't keep
Anchors away
I promised I'd stay
Against my every instinct
I'm in the black till the day sinks
I won't go down, down
To that dirty part of town, town
I just want to stay clean, clean
You don't know what I need, need
You don't want to know
Double six
Double six, double six
The jig is up the fight was fixed
I'm on my way, I'm in the sticks
I won't go down, down
To that dirty part of town, town
I just want to stay clean, clean
You don't know what I need, need
You don't want to know
Trust me
You can't trust me
You don't want to trust me
'Cause you can't trust me
No, no
Meet me by the river
I'm sorry Mary Jane
I thought that things could be different
What else can I say?
But I recall watching you
Walk down the aisle
And I recall the way the flower girls
Made your mother smile
