In a narrative essay, an effective opening transition phrase sets the stage for the storytelling that follows. "At first" serves this purpose well by introducing the beginning of a sequence, suggesting a progression of events or thoughts. It creates an expectation for a narrative that will unfold over time, allowing the reader to anticipate development in the storyline.

The other options do not serve as effective opening transition phrases for a narrative context. "Furthermore" and "In addition" typically indicate continuation or addition to previously mentioned ideas, which is more suitable for essays focused on argumentation or exposition. "For example" introduces specific instances or illustrations, which fits better within the body of an essay where you're supporting claims instead of leading into a narrative. Therefore, "At first" is the most appropriate choice for initiating a narrative.
