You could make something based on colors! You know, to go with the Dark/Light thing? Maybe provinces, or animals (bring back the sparkling rainbow unicorns!)

I’m sorry I bottomed it by accident, so TOP!

You could maybe base the realms off the 5 elements, earth, fire, water, air, magic (I'm counting magic)... Oh, sorry if this is annoying, but can we know a bit more about the characters? 

Part 1, chapter 1

Zedar
was polishing his master’s boots when he realized it was his
birthday. He thought about being 14 for a second, then he went back
to polishing. You see, he was Kelddath Darkmire’s -the 11th
RealmMaster’s- squire. Which was most definitely NOT fun. He presented the boots to the DarkMage, who roared at him “THESE
AREN’T CLEAN!!!! THERE IS A SPECK OF DUST ON THEM!!!!” the
DarkMage had been a little -just
a little, mind you-
unstable ever since his son
and daughter had
disappeared in the middle of the night three years ago. Zedar
finished polishing for the second time and yet again presented the
boots to the DarkMage “AGAIN?!?!?” the RealmMaster roared “THERE
IS A SPECK OF MUD, RIGHT THERE!!!” he pointed at it, then slapped
Zedar three times on the face.
Zedar felt something powerful welling up inside him, it
felt...Strange, but not painful. Zedar stood up, his eye glowing
gray, “WHAT THE 1ST
REALM-MASTER!!!” Kelddath yelled “IS GOING ON!!!” Zedar began
to float in the air, his eyes emptying of all color and instead
glowing white. Then Zedar stretched his hands out to the sides and
nothing happened. But then Zedar raised his face toward the sky and
summoned a tornado. Now,
this was right about the time where Kelddath had stopped gaping at
Zedar and begun to shoot lightning bolts at him, which Zedar was
deftly deflecting with gusts of wind, also, the DarkMage was
extremely confused and scared, and you must feel at least a little
sorry for him. Now he shouted “WHO THE 1ST REALMMASTER ARE
YOU?!?!?!?” and then the tornado i
talked
about earlier burst through the wall behind Zedar. Zedar then pulled
it into himself and unleashed it in the forms of armor, a magnificent
white Pegasus, and a sword… you really must feel sorry for
Kelddath at this point. I’ll spare you the
gory details of when Zedar chopped Kelddath’s head off, but I will
say that there was blood, the armor and the sword disappeared, and
Zedar slumped to the floor.

Aztarg woke up flying. For a second, all he could
think about was the fact that he was flying. And flying. And flying.
Then more important questions came up: Why am I flying? How do I
know what that means? HOW am I flying? How do I know what that means?
Where am I? How do I know what that means? Who the heck am I? How do
I know what that means? Then
Aztarg saw a speck in the distance
“what’s that?” he asked himself “How I know what that means?
Also, WHO THE HECK AM I!!!” the speck was close now, and it was a
giant portal. “A portal?” Aztarg asked himself “how do I know
what that m-” his words were cut off as he entered the portal,
there was a enormous CRACKA-CRACKA-BOOOOOOOOOOM!!!!! and
Aztarg was falling. Falling. Falling.

“IIIIIIII’M NOOOOOOT
FLYIIIIIIIINGGGGG ANYMOOOOOOOORE!!!!!!!” yelled Aztarg

“HOWWWW DOOOOO
IIIIIII KNOOOOWWWWW WHAAAAT THAAAAAAAT MEAAAAANS!!!!” a few
townspeople looked up disinterestedly, then scrambled out of Aztarg’s
way, screaming. And then Aztarg flung his hands out to his sides and
summoned wind. So much wind. Aztarg formed
it into a ball of wind and surrounded himself with it. However, he
couldn’t stop his momentum and crashed into the ground, leaving a
house-sized crater. Nobody was hurt, but half the market was
obliterated and the townspeople were mad. Aztarg stared at his hands
for a second, yelled “i am having SUCH a BAD day!!!”
and ran off, jumping over buildings
in a single bound (and no,
he’s not Superman) as he
ran from the angry mob chasing him.

Alyson
warmed her hands by the fire, wondering when Frodar would be back,
Alyson had wanted to hunt that day, but Frodar had insisted. Now it
was pouring rain so hard it looked like they had been transported to
the Realm of Water. They had been stranded in this weird,
unpredictable realm, ever since they had fled from Kelddath and the
rest of the DarkMages and
her brother had died.
Frodar had finally returned, soaking wet, a wound in his shoulder,
empty-handed. “sorry I couldn’t find anything” he said “all
the animals were in burrows or above the clouds” “nothing? How
did you get that wound then?” “couple o’ DarkMages” he smiled
grimly, without mirth “let’s just say they won’t be attacking
anyone...ever again.” Alyson sighed “great. Just great. Now we
have mages to worry about.” “yep.” he said “it will be rather
annoying. Anyway, how’s your magic coming along?” “i managed to
drill a large hole in the back of the practice chamber...it collapsed
though.” “hmmm… how big?” “about ten feet back, five foot
radius” “not bad!” he cheered up significantly “i found
something on one of the DarkMages that I think you’ll be interested
in.” “What?” Frodar took something out of a small waterproof
pouch “it says ‘three days ago, in the Realm of Keldar, Kelddath
Darkmire was killed by his squire, Zedar Flamesword-’” “Zedar
killed my father?!?” “yep, and wait, it gets better. ‘Zedar
showed extremely powerful wind magic, summoning a Pegasus, armor and
a sword.’” “ZEDAR?!? this is my the same Zedar I’m thinking
of, right?” “yep. And then two days ago, a strange boy crashed
down in the Feldagard Market and destroyed half of it.” “HALF of
it? But how could a single
boy
crashing down cause a half-market-sized crater?!?” “he surrounded
himself with wind to keep himself from being hurt, and here’s the
best part: this boy was never born, according to the Database.” “oh
my Realms.” “exactly.” then a boy stumbled into the cave
“Alyson? Frodar? Is that really you?” “yes, but who are you? If
you’re working with the DarkMages I’ll-” Alyson placed a
steadying hand on Frodar’s arm “Frodar, if he was working with
the DarkMages, he would be armed and wearing more than some cotton
and a tattered old leather cloak.” then to the boy “and who are you, and how
did you find us?” “i-I’m Zedar, how I know where you are is
because I saw the RealmMasters discussing how best to capture you,
they know where you are too...and they’re coming to capture you,
Alyson, and they don’t really care what happens to you, Frodar as
long as you face ‘justice’” as he said the word ‘justice’
he made air quotes “just let them TRY.” said Alyson. “Zedar,
how much control do you have over your magic? “as long as I’m not
freezing, I can make it very strong, and I’ve got Zephar.” he
whistled, and the majestic
white Pegasus came swooping through the cave
entrance.

Sorry, i haven't written much, Inktail, the story will slow down a little bit in the next chapter, but that chapter will introduce the rest of the story.
