This is a submission from my fictional story world involving one of the most iconic creatures. The Felis Magus have been a favorite among my players in our TTRPG adventures.

I decided to them here to share and hopefully entertain others! I posted the 5e rules that I use for them within the body of text. You're welcome to play one or modify the rules to make it playable in yours or another GM's campaign. Please let me know if you do! I love to hear about the stories people create and share.

I also appreciate credit though I don't expect you to tell your friend group about me. Just don't claim my works as your own please.

Brief Historical Background

Just after the Age of Obscurity, a worldly guardian confronted the great dragon of
magic. In their battle the golden magical dragon accidentally imbued a lone cat,
transforming the mundane creature into one of magic. And thus the Felis Magus were
born.

Felis Magus are the lore keepers and true scholars of the world. They did not exist
during the Age of Obscurity. Felis Magus have studied and documented it better than
anyone else.

They are everywhere in the world. From urban landscapes to remote mountain regions.
They love wanderers and they love to wander, there is no environment you won't find
a Felis Magus inhabiting. Everywhere they go they bring their magical charm.

Physical characteristics & Lifestyle

Small felines with natural inclination towards magic. They live anywhere and
everywhere, usually in occult organizations or within the Great Houses. Felis Magus
stand upright and are the world's renowned practitioners of magical art and craft.
They are magical creatures. Born into a body of blood and bone, but with the touch
of arcane flow. Able to harness and practice magic just by their nature. They die
of natural age unlike true magical creatures, the longest lived Felis Magus was 25
years old.

Felis Magus are short lived and curious creatures. They are known for their chaotic
nature, but also their desire to create and learn. They strive to perfect their
talent and profession.

A young Felis Magus will leave their family and go out into the world either alone
or with others from their home. This is a required journey to climb their societal
ranks and become a master in any field of trade or magic.
Felis Magus are adorned with a trademark Pointed Hat and Oversized Robes. It is a
choice of style and universal in their culture, everyone wears slightly oversized
clothing. Though as of the new era there has been a shift in Felis Magus dress
code.

Felis Magus Society

General History

Felis Magus Society is ungoverned and ungovernable. Even among the Great Houses
there is no way to maintain order except for a core group of leadership, known
often as The Masters. Mentors or successfully graduated Felis Magus that aren't
masters are referred to as Hats, which are community leaders charged with their
local communities. No one, not even the wisest of scholars or mightiest of kings
can satisfy a Felis Magus’ curiosity forever.

Felis Magus society historically works on a basis of taking the best sorcerers
among them and giving them all the advantage of education and higher learning,
turning Sorcerers into Wizards - or as they refer to them, a Scholar which are then
turned into candidates for Mastery. There is also the Coming of Age ceremony. Once
a Felis Magus is nearly no longer a kitten, they will band together and leave their
homeland and travel abroad to learn magic and experience the world. They often
return years later, but sometimes settle down in new lands to continue their study
or practice. This ceremony is referred to as their Graduate Quest. It can only be
completed by attaining competence in at least one field of magical trade or by
showing mastery in using their elemental aura's potential.

A Master is a Felis Magus that can cast non-elemental magic. This is acquired in a
variety of ways for a Felis Magus. The most common way is to drink the blood of a
powerful enough magical creature. The other is to create the tools necessary to
cast non-elemental magic. To be officially reconigzed as a master a Felis Magus
must provide a spellbook to be reviewed by a council of masters.

Outlying Communities

There are countless Felis Magus communities that exist out in the wild. A lot of
times the wilderness is inbetween the walls of a castle library as much as it is a
secluded grove or mountain side. You’ll often find loners or small groups plying
their trade or wandering the alley ways. Sometimes you’ll even find their
sanctuaries within civilization, hidden taverns or libraries operating out of
vacant buildings. If the Felis Magus aren't welcomed officially then they will
operate unofficially.

These communities study magic as Felis Magus always have. Through the stars and the
study of the elements, or sneakily from the libraries of other civilizations. Some
do engage in more supernatural or elementalist proficiencies, skies the limit for a
kitten born with a curiosity to satisfy and the natural inclination to do so.
These kinds of Felis Magus are the ones you'd see roaming coast to coast, selling
goods and plying their trade to fund their studies or operating questionably within
the borders of settlements that do or don't welcome them.

House Paragon

It's believed that House Paragon may have been started by a non-Felis Magus and in
fact might be an extension to the Spellsword Legion, the notorious pirates of the
Three Oceans.

It's largely shrouded in secrecy. They have a focus in the esoteric arts - which is
the keyword for Astral, Necromancy and a focus in Aura magic. They generally
despise the use of physical tools to enhance their capabilities. Though there has
been a shift with their ethics and practice as many House Paragon Felis Magus have
been practicing golemancy and wielding silver tools.
Historically, House Paragon was a number of cults from central Mundland that felt
they were being targeted by the Archmage's Council unfairly. After House of Nine
Hats was formed they followed the idea by forming House of the Paragons. At the
time, Ash Dragons were still Orange Dragons and the Rumfields - the great central
plains of Mondland - was a land of smoke and fire. The Masters of House Paragon
were students to Kalder of the Fire's magic (the Draconic Archmage) and believed,
just like the Dragons, that their Felis Magus bloodline is what gave them power.

House Halvarron (House of Nine Hats) pronounced Hal-var-on

The first of the great houses. Nine Hats himself was a Felis Magus Gold Blood,
which is a Felis Magus that is incapable of possessing magical potential. Unable to
cast magic, he was exiled by what would very soon become known as House Paragon.
Nine Hats studied the ancient arts of Golemancy under one of the Archmages and
learned the ancient art of gemstone embedding. He used these trades to create tools
of elemental power, which granted him the ability to wield magic externally and
thus became the first ever Wizard among Felis Magus. He and his nine friends formed
the first great house and began teaching their practice freely to everyone, even
non-Felis.

They very quickly grew into a large group and founded the City of Merunin (Mer-unin). A bastion of scholarly pursuit and enlightenment, in a time when such a thing
was rare.

House Sugar and Spice

House of Nine Hats is recieved warmly amongst most Felis Magus whereas House
Paragon is a scourge among their kind. Not wanting to be absorbed into the war of
the two houses the House of Sugar and Spice was formed. Once a small gathering of
communities became something greater when Paragon annexed their firsty territory of
note, a historical rune stone site that many Felis Magus across the continent of
Mondland travel to. The site held a rare star chart, which was one of the few
places young Felis Magus kittens could go and learn more abstract magical arts.
After the annexing the small communities began to recieve larger when
outlying communities began sending competent Magus to wage war against House
Paragon. This united a great number of communities which resulted in the formation
of this great house, named after two of the many things Felis Magus enjoy.
In short, House Sugar and Spice exists to preserve their history, culture and slow
the expansion of the other great houses, specifically House Paragon. It follows no
law or regulation. identify each other by adopting ridiculous names, often
mocking the Great Masters of Paragon or the Scholars to the House of Nine Hats.
