Trimonia is a strange plane, or should i say planes? Trimonia is actually three planes that were crashed into one, creating a new one. There are still the remnants of those three planes though.
The planes were the shaded plane, the celestial plane, and the rune plane, and the place where these three combines is called the walled plane.
The shaded plane is an ancient prison for demons and horrors, where they were sent there by ancient planeswalkers, the celestial plane is a plane used by angels as a sort of headquarters, but they lost their ability to planeswalk, so they trapped themselves.
The rune plane is a very mysterious plane, inhabited by the D'yer, a race that doesn't have a definite form, and not much is known about them.
Before each of these creatures realized the planes had collided, a group of mages, warriors, scholars and an ancient planeswalker had used a machine that allowed non-planeswalkers to travel to other planes, and they built cities on the strange walled plane. All was peaceful until each of the races learned that they could leave their planes, they all went on a terrible rampage on the walled plane. After years of terrible calamity, the mages and the planeswalker finally created three walls to seal each of the races behind them, back into there planes. Each year, a spell would be cast on the walls to keep them strong, and the civilization on the planes was peaceful until the mages died, and the cities became lazy, forgetting the spells that kept the walls together, but nothing happened, so they continued to live in their naive bliss, until the walls began to break, and each of the terrible races stole the scrolls that held the spells to reinforce the walls, and waited until the walls broke for once and for all so they could find the ancient machine the old settlers used to come here, so that they could as escape Trimonia and do their biddings on the multiverse. And then...
You come up with the story! Tell me about characters, about places and other events in this plane. Create cards that describe them, and those with the most creative cards and stories will receive treasures that even the D'yer don't understand.
