I don't get why people even care what Ivan thinks.

He didn't know where Lumen Histoire is or what it did. He only knew the name and that it was super secret and should only be known by the Guild Masters.

It being "Darkness" is a completely baseless speculation on his part. His twisted mind most likely can't conveive of something being hidden without being evil.
