Though not quite a Divine (it's a new Species of Special Horse) the next set is going to be the Legendary Horses. They are like Divines in how they work (ex. Don't count for EC Prestige, can only enter 1 regular comp. a day (But unlimited Divine comps.), can't be customized with items like the Golden Apple, etc.

In this post here - I brought forward pictures and the FAQ I wrote about the Legendary Horses.

~*~
This next part is a copy/paste of the topic on PReprod about them:

We introduce a new series of rare horses: Legendary horses. These 5 horses are very special and each will be in line with a story. These stories were written by an author who will not be revealed during the test period so that we can keep the surprise on the live version.

The first story will be revealed, chapter by chapter with progress of the collection of horseshoes in the Grand Challenge. The remaining stories will be revealed through other competitions in the future.

On the Directories page, you will find a link to a page that describes all five Legendary horses.

The Legendary horses have some peculiarities that we invite you to discover with Altair.

When a new chapter of history is unlocked, a banner appears on the main game page.

Altair


Altair is the first of five Legendary horses.

He is a beautiful Mongolian stallion and you can discover it's history and that of it's young rider, chapter by chapter on the live server when the competition will be launched.

How can I turn my horse into Altair?

During the contest you can win tack unique for Legendary horses. You can give pieces of Altair equipment to one of your horses. When you place a piece of equipment on one of your horses you can no longer sell it.

►You need to complete the first Altair before you can place Altair tack on another horse (if you want a second Altair, you should expect to complete the first).

►You can replace the Altair equipment by other equipment, but in this case you will lose the Altair equipment.

►When you have five pieces of equipment, your horse becomes Altaïr. It keeps the same features but its powers double.

►The horse can receive Black Market items with the exception of Morhpeus' Arms and Nyx Packs, breeding items and customization items.

►Registration for the Grand Prix is not available but the horse can enter competitions.

►During reproduction, cover offers are lost. If the converted horse is a mare in gestation, it will lose the foal.

So pay attention to the horse you turn!

The horse turned receives the Philosopher's Stone and becomes immortal.

What is Altair?

Altaïr offers 24 VIP from time to time to its owner: Some days he can drink twice. When drinking for the second time of the day, it offers 24-hour VIP. If you are not eligible: get the advantage of Altair makes you eligible. If you are a VIP, your subscription will be extended by 24 hours.

VIP players, Altair offers:

Altair allows you to automatically manage the distribution of your EC missions.
When there is at least one resource to be collected in your EC (greater operating capacity than 0), the mission assignment focuses entirely on resources. When there are no more resources, missions focus on the lessons.

Star of the immortal power

On the legendary horses, you can see the star of the immortal power.

When a horse becomes a legendary horse, you receive the branch of a star. Each branch can only be obtained once. For example, if you turn 2 horses Altaïr, you will receive only one branch of the star.

When you have collected the 5 branches of the stars (and therefore get the 5 legendary horses), you can activate the star.

Upon activating the star, all horses owned by the player receive the Star of immortal power bonus, which gives them +10 in each skill. The star can only be activated once.

We will get the balloon fight and the GC may or may not run at the same time. I expect one or both to start on Monday the 20th.

If the GC does not start Monday it will start the Thursday 23rd or the following Monday the 27th

a small promo, water balloon fight where UFOs become water baloon with gifts you can throw at your friends (see an UFO, click it, it reveals a brown saddle, throw it at one of your friends and then both of you will have that brown saddle, for example)
The numbers here are likely to be different, in similar promos, they used to differ from server to server.

One player transformed their horse into an Altair that had a Companion. That Companion remained so here is the reply and should let us all know what we keep and what we lose.

Please be advised that this is not a bug and is functioning as intended. The transformed horse does keep it's family tree and bonuses from BMI's . The exceptions to this are Morpheus' Arms, the Nyx Pack and all breeding customization items.
