Why is my reflection someone I don't know

You launch at the beast, the guide at your side. The two of you struggle and fight the monstrosity. It's body feels armored beneath your fangs, but eventually it gives and the guide allows you the killing blow.

You return to the surface and notify the tree's residents, they cheer your praises and patch you up. They adorn you with a flower cape the spider wove for you, asking you to stay for a while. They throw a feast in your honor, and as the sun dips low, you feel it is time to leave.

As you leave the celebration, your guide follows. It is their time to leave as well. They nod and bid you farewell, walking away with a hum until you blink and they are gone, only a few fireflies buzzing lazily where the guide once was.

You receive the following rewards for successfully completing this adventure:
- Dire wolf character pass (for defeating Greg) [ALREADY GIVEN OUT, 1/16 - nyx]
- Item reward from Stage 4 (to be revealed)
- 82 Gems from Stage 2
