More information came to Elric with regards to the world of the most secretive and bizarre elemental realm, however, most of them were not that significant for him.
The reason the planet itself was not available via plain sight is because of an ominous dark cloud that has been covering the entire planet. It was too black that it was able to absorb light causing it to blend into the vast dark-violet sky of the Elemental realm.
Not to mention, those clouds also serves as protection that will unhesitantly bombard anyone who dares to approach the planet from any side. Unless one had authority from the Lord of the Lightning Elemental Realm, forcing one's way inside is basically a suicide attempt.
Elric continued to watch how Forgar was first introduced to the unique world, with the help of the Lord, he managed to adapt to the new place and power in no time.
