I might as well say a few things we know about Alatreon.
 * Alatreon actually doesn't appear in legends or any form of documents like other Elder Dragons so it was never known.
 * Alatreon can cause blizzards, storms, blazing fires, and lightning storms as its natural disasters which can all be seen in the Sacred Land while fighting it.
 * Its been rumored for years that there is an Alatreon Subspecies and this has been hinted at throughout the 3rd Generation games. Supposedly if its real, it has the ability to produce blue fire.
 * In Monster Hunter Tri, Alatreon was said to have been seen in the Great Desert.
