Acicade Castle
Acicade Castle is a fledgling castle from Castle DesCas. With the main land in growing chaos from bandit attacks and ravaging mercenary bands, a small group of knights volunteered to get away from menial jobs restore one of the older castles in it's former splendor. Acicade Castle, set on a hill in a luscious forest was chosen from several older, abandoned castles as it's location was very close to what was believed to be the hideout of a local band of mountain thugs. To warrant their safety while getting started, the knights made an agreement with the resident ninjas for protection that would later be returned in a joint project to have some knights train extra as ninjas to patrol the forest.
Though only recently restarted, the organizing is progressing quite smoothly. There are already clutches open for aspirants and there are a bunch of pet adoptions including faery draks, vulpas, spiders and prutses.

Chindor Castle
On the smallest island of Icarus lies the young castle Chindor Castle. Two Vikings, Ulf and Scareh, found this little place when they landed on Planet Icarus, after days of traveling with their small boat.
It didn't take long before Ulf and Scareh heard about the strange drak that had never been seen, but that everybody knew from the villagers living on the small isle. He had feathery wings, instead of the normal ones. He only showed himself on foggy mornings on the isle near where the castle was build. 
When Ulf went to explore this so called strange drak, he didn't find it. But what he did find, or better what he heard, was a soft whisper telling him: "Chindor".  From that moment on, the isle was called Chindor and the castle on it Chindor Castle.

Dawn Castle
Dawn Castle is situated on a cluster of islands in the east of Icarus. Boasting to be the most romantic castle and the place where the sun rises on Icarus, Dawn Castle was founded by High princes Raf on Rain Nelladuar and Xander on Day Crischisen. The theme of the Castle is inspired by Earthen culture (namely Ancient Roman and Greece) as it's founders were originally Eartheners who by some mysterious means were transported to Icarus and paired. The warm waters around Dawn also host pirates and rebels. Some of these have paired with draks and serve as peacekeepers in the area (though it's not always clear which type of pirate you meet). 
Head on over to Dawn Castle for fairy drak, vulpa and tropical fish adoptions.

Castle DeCorvo
Castle DeCorvo, castle of the crow in Portuguese, was situated in the tropics of Planet Icarus, nestled in a small basin between two shallow peaks, it was sheltered from harsh winds and boasted a warm and wet climate. The castle protected two villages: Lareira Village, a rural town and Nocti village, a bustling business center famous for it's vulpa breeding. 
All seemed to be well, but the lack of communication from the rest of Icarus led to a rebellion of the surrounding villages that ended in the killing of many knights as most were unable to attack the villagers. Among them also High Princess Derakoh. High Prince Kireshan ordered his men to leave him in his sorrow and lock him in the room where the body of his wife laid. Legend tells that High Prince Kireshan impaled himself with the sword of his beloved Derakoh, and that their ghosts are still wandering in the castle ruins.

Castle DesCas
DesCas, an underground oasis, lays on an island near the crash-site.  When on a run to report Nex Necium in the small desert area, gathering for an attack. Zander, a young nomad man of 23 years old, first found this little oasis. He stayed there to recover before his final trip that would lead him to a nearby Castle on the main land. It was a beautiful place where he fell in love with the dry nature of the desert. Later, after he had impressed Night Perini, he returned there to start his own castle.
DesCas mostly protects nomad tribes that live on the fringes of the desert, as well as some small fruit-growing communities that have sprung up in recent years. It has faerie drak, vulpa and saharel adoptions all within the underground castle.
No descriptions of DesCas would be complete without at least mentioning their extravagant hair stylist. This man, who wishes to remain nameless for now, was the master mind behind the old 'Lara' style and now seemingly has gotten his hands on a bunch of old My Little Pony collectibles, though he insists his new hairstyle is completely his own invention and that it should be called 'fluff'.

Castle Dun Keiba
Castle Dun Keiba, literally Castle of Racing, was first established as a strictly human castle that overlooked the only large permanent body of fresh water in the savannah surroundings. It was only when nex necium attacks started occurring more frequently that it requested for an armada of draks to support the humans. From that day on both humans and draks have done well at Dun Keiba. The current High Prince and Princess are Almiron and Dominica, half siblings with each their own interests and areas of expertise.
The most noted thing at Castle Dun Keiba are their Racer Draks, a species of wingless reptiles that closely resemble draks, that are used as mounts in elaborate races in the area.

Castle Lanaara
History: Unknown, used to be run by draks solely, now humans have taken over the rule. Lanaara is a mountain castle, with frequent snow and chilling temperatures. Most noted is the wild colony of draks that resides near the castle and that sometimes open up their clutches for pairing. These draks have less of a mane, caused by the frequent fights, and seem to be of Sidra stock. Recently the draks a the mountain castle have convinced the wild draks to let humans mind pair their draklings.

Castle Lav'intay
Castle Lav'intay, one of the first castles on Icarus, was settled on a small island surrounded by rainforest. It was run by princess Mihani, who faced with a deadly dilemma, chose to seal off her castle from the rest of Icarus to make sure the disease that had infected most of the knights and draks at Lav'intay could not spread. A few lucky knights on business to other castles are all that remains of this proud and valued castle that only had one public clutch. It was also the first castle on Icarus to close and therefore will remain in our memories forever.

Drockh-Tallahn Castle

In fact, Maile and Farai started the castle after they met and befriended a clan of wild draks who shielded them from the mob members that were after them. Currently this castle is accepting aspirants and also has faerie drak and vulpa pet adoptions.

There are a few nomadic tribes that frequently travel past the castle, but none has ever stayed long.

Sidra Castle
Sidra Castle, one of the two first castles on Icarus, was led by High Princess Aleia-Nevolei on Day Amathist and High Prince Vance on Night Tuonov.

Though closed now, the pioneer castle won't ever be forgotten by it's descendants who still fly free in the sky of Icarus.
