You see Wilbur in his cave looking at some shiny jewels. He doesn't seem to notice you yet. He is widely feared across the world for his power and species. Especially his aggressiveness. It may be best to stay away from him. But if your feeling daring or suicidal then go for it.

Wilbur seemed very interested in his shiny jewels. He seemed to be cleaning them or something. He probably wouldn't pay any attention to you. Unless you brought his attention to you by speaking to him or something.
