Star war exodus. What is this?

I found on a very holy canon website, in an article about the star forge the mention of the celestian.... And a giant space station that have been used to scale the star forge....
Later in my rechearch on the Rhand sorcerer I found this :
http://starwars-exodus.wikia.com/wiki/KR0_Stone_Soul
The aspectt remind me the description of the pawns used by the rhand sorcer described by Holonet.......
There the mention of celesta in this page....
http://starwars-exodus.wikia.com/wiki/Celesta

O.K may my friends of Holonet laugh at me when I ask them.... But WTF is this?

I'm pretty sure this is like... fanon for a star wars RPG forum or something.

Is this legends or new canon?

This really fanon sometimes.... (Looking at the Freedom nadd article...)

But this is the only website where I found information on celestia......

They alaso have really rare information like the Venator MK-II wich in fact is not really name like that but exist...

I'm schearching this guy made one :

He also made a star forge a death star a real size super star destroyeur.

Find by yourself.. I think this is the legacy one...
