The reason they got there was because Red was right from the very start. The region below the centermost star on the skies was the center of this realm. It wasn't anything surprising that the Blood Lake could be found there as well. That's how they didn't come across any problems coming here. Also, Gulan was a Blue Luan, a Demon Bird, so Red could keep them concealed while Gulan flew their way over.
"I...remember this place," Red said in a low voice. "That doesn't make sense. The Bestial Sacred Ground that I remember should be the other one. The Blood Pond wasn't a lake either. Still, it's like the memories are popping up on their own."
Gulan looked at Red, who seemed somewhat lost, and said, "Isn't that a good thing? It means that you're getting closer to the truth of your identity. Perhaps you can find who you are in this place."
Red nodded. "Let's hope so."
"Then? What do you remember?" Gulan asked, changing the topic.
