Guide to the Immortals

the Glantrian Highlands. In 1700 BC some elves found
an ancient Blackmoorian artefact in that region, and they
caused its explosion when they tinkered with it. The
resulting radioactive rain and the nuclear winter that
devastated the whole region turned it into the modern
Broken Lands. The so-called Glantrian Catastrophe
affected even the farthest reaches of the nearby Ethengar
Steppes forming the Land of the Black Sand. The elven
survivors dug underground, in at least two directions, to
flee the disease and destruction. Atziann was the sole
survivor of his clan, probably because they were
responsible for finding the artefact and triggering its
destruction.
After years spent wandering underground, an
embittered and vengeful Atziann emerged into the Azcan
Lands in BC 1650 and began to live under the Red Sun
disguised by his magic. He became slowly fascinated with
the Azcan culture, and, after years of living among the
Azcans and building his net of conspiracy, Atziann finally
left Azca when he made contact with one of Thanatos's
Burrowers, who revealed him the path towards
immortality in the sphere of Entropy. When he returned
to Azca after his travels took him all around the Hollow
World, he used his extensive net of spies, thieves, and
conspirators to usurp the priests' and Emperor's power
and to create a new religion that would have helped him
ascend to the top of the Azcan pantheon once he became
immortal. Thanks to his deceit the cult of the new god,
Atzanteotl, established a sense of unrest and rebellion
among the lower castes and later got hold of the hearts
and souls of the more corrupt priests, who organised a
true uprising against the established rulers and forced the
rightful Tlatoani, Atruatzin, to flee from the capital city.
This event marked the peak of Atziann's corruptive
power as a mortal and guaranteed his ascension to
immortality in BC 1500. He immediately took the role
he had tailored for himself, and under the identity of
Atzanteotl he began to spread his words of hatred and
strife in the world. But Atzanteotl had not forgotten his
old enemy Atruatzin, and he tried to corrupt him with
promises of eternal life and power. When the wise old
emperor refused to side with him, preferring to defend
the ways of the old gods, Atzanteotl sentenced him to
death for his insolence. So he sent his minions to
Atruatzin's fortress of Quauhnauhac to capture him.
They massacred all the resistant forces trying to capture
Atruatzin, who managed to flee below ground.
Atzanteotl's priests silenced all those who dared speak
against the new order and crowned a new puppet
emperor in the name of their god. They also rewrote the
historical records of the Azcans, thus obscuring the
importance of the old gods in favour of the new one.
Atzanteotl became the only true sun of the new Azcan era
characterised by human sacrifices and brutal rituals.
However, when Atzanteotl found out that Atruatzin
was still alive along with several allies, and that they had
found shelter in the ruins of Aengmor (now renamed
27
Mictlan by Atruaghin, the city of the dead), the former
capital of Atzanteotl's elven kingdom in the outer world,
he went mad with rage. He contacted a group of
underground elves and led the unsuspecting refugees
through the caves leading to the Hollow World, with the
promise of a new homeland. The Schattenalf clan found
Mictlan and they assaulted the citadel, killing all the
humans living in the sacred temple of their new god,
Atzanteotl. However, once again Atruatzin was able to
flee and found refuge in Xochiquetzal's court, thus
hidden from Atzanteotl's watchful gaze. Atzanteotl
ordered the Schattenalfen to rebuild the city, and when
they ended their task, he caused great earthquakes that
killed many of his followers, forcing the survivors to
move away from the city and find another place to settle.
He then moved the city towards the surface of Mystara
without destroying it, and placed it floating on a lava
pool beneath the Broken Lands, where it was later
discovered and inhabited by humanoids, who renamed it
Oenkmar and converted to Atzanteotl's cult. Meanwhile
the fleeing Schattenalfen emerged first in the caves of the
Kogolor dwarves, beginning a vicious war against them.
When Denwarf the golem was sent to help the dwarves
and the elves were outnumbered, Atzanteotl guided the
survivors to the grottos near the southern border with the
Empire of Azca. This began the eternal rivalry that turned
into a perpetual state of war between the Schattenalfen
and the Azcans, worshippers of the same immortal (a
situation Atzanteotl greatly enjoys).
Atzanteotl was later responsible for the bloody feud
between the Sohktari (manscorpions) and the Enduks
(winged minotaurs) of Nimmur, and he managed to
convince the Sohktari clerics to strike the old Enduk allies
in their back, in order to drive them away from Nimmur
and conquer the land for themselves. The Sohktari
betrayed the Enduks and established Menlil (Atzanteotl's
name in Nimmur) as leader of the new Nimmurian
pantheon, thus earning Idu (Ixion)'s terrible curse that
forces them to avoid direct sunlight or be burned to
death.
Now Atzanteotl's master plan is the corruption of the
Shadow Elves and other humanoid races. He wants to
create a schism among Rafiel's followers and thus increase
his influence among the inhabitants of the underground
of Mystara, hoping that one day all the outcasts living
underground will emerge united under his banner to
bring utter destruction to the creatures living above
ground.
Personality: Atzanteotl is fascinated by the process of
corruption and he especially loves to see how any
kind-hearted person can fall into the abyss of Evil and
regret thanks to his machinations. Often, he loses interest
in one project and starts looking for new ways to spread
evil. His final goal is the complete annihilation of life on
the outer world, and especially the destruction of all elves.
Patron: Thanatos (who now considers Atzanteotl a
deadly rival)
