Knowing such a place, Angus couldn't help but be intrigued at the secret of this Losvertisch. On the other hand, he also didn't want to pry too much on it.
Despite his huge curiosity, he still adhered to Master Benjamin's advice. If it is heavily sealed, it means the thing inside is too dangerous for the outer world. Otherwise, the seal will be broken a long time ago.
With many sub-dimension appearances, it proves the seal is strong and has never been broken for who knows how long. With such a powerful seal, Angus knows the thing inside is equally powerful.
As for the rumor about the seal getting weakened from the Guardian, he assumed it should be a seal to prevent Gram and monsters from coming out, not the genuine seal of Losvertisch.
