You're either ignoring or unaware of something that I see as a fundamental difference between these two things.That the Orc fails to dodge is something outside my immediate character. Yet, by rolling an attack, I can make it true in the fiction that the Orc failed to dodge.
Remembering that there are Dwarven forges is something that is inside my immediate character. (It's in my head.)
The Orc is already present in the fiction; it's an established element with which your character is interacting. That said interaction happens to be combat doesn't matter, it could just as easily be a conversation over lunch or a simple wave as you pass each other by; what's relevant is that it is occurring at all.
The dawrven forge is an attempt to establish an entirely new element that's not already present in the fiction, in hopes of being able to interact with that element at a later time.
