Siyauon - The Shadow Plane

Just as the Celestials in the Celestial plane (Alishar) are the result of dragon-spawn souls reaching the upper plane. The Fiends within Siyauon are the result of dragon spawn with the taint of Saiyiden and drawn to the lower planes. These unfortunate dragon-spawn quickly completed the corruption their mother had started, as they became twisted beyond recognition, their darkened souls formed into the fiendish creatures of the shadow realm.

Along with fiends, the expanse is home to uncountable demons, creatures birthed by evil itself for a singular purpose, to breach the mortal planes and claim them for the The Void. These two forces try to breach the planar barriers and reach the Material Plane, fortunately for the material plane, incursions are infrequent and short lived, the demonic and fiendish creatures are either quickly destroyed or soon run out of negative energy.

If these two factions ever worked together then it would spell doom for the Mortal Plane and beyond.

Siyauon the Shadow Plane
Infernis an Afterlife Plane
Form: A sphere of negative energy

No mortal being can survive here, but should they get a glimpse it would appear to them as a place from their own memory, cast into shadow and with all their fears taking shape. To stare too long at the impossible would send the viewer mad, which it has done to many a wizard who thinks they know better.

ABOUT US

THE CONCEPTION

Terrainia started off in 2004 as a single island for a role-playing game (using a well-known and popular third edition rule set). This island became wonderfully detailed, players would recognise who they were dealing with when suitable miniatures (made by another well-known table-top games company) were placed on the table. But eventually the players finished the campaign, and managed to slay the dragon, or so they thought.

So with the campaign over, but the desire to continue burning ever bright, further areas were designed and planned, and over the course of five long but enjoyable years the world grew exponentially. At its peak of these five years there were six regular groups, around forty players, two dungeon masters, and a world as large as Earth drawn up and with huge levels of detail.

THE EVOLUTION

While that is where Terrainia was born, now twenty-one years on and the development hasn’t stopped, we began to construct this website in 2010 as a resource for our players to use, then in 2020 (during the world wide pandemic) our founder took the opportunity to flesh out the world even more and add this to the website during which thoughts turned to sharing Terrainia with the rest of the world.

It was at this time that the founder began to commission artists, budgets were low, it took time to find the right artists with the right style, but over the next few years the main cast got made, the deities, the primary heroes and villains, then monsters. it was important for the founder that all artwork was theirs, monster design was theirs, and in turn game systems were theirs, we did not want to copy or reproduce existing systems

Along with the game world, contributors are writing novels and designing games, all set within Terrainia, at the time this page was last updated there is no less than seven different games/books in production, and soon will have link to these games/books for you to immerse yourselves within.

So that’s us, we hope you enjoy the site, if you want to give us some feedback why not .

THE FUTURE

After this first wave of games and books who knows? but one thing for sure is there is plenty of material and our aim will be to share this world with as many fantasy fans as possible.
