At a gathering of the three major houses of the Empire, Haggra used the Vapours to show everyone who would help them find the Chaos Emeralds. Master Scholar did not recognise the image of Sonic the Hedgehog in the cloud, believing that someone like him would not be heard of in the House of Knowledge. Although Emperor Ko-Dorr knew him, he feigned ignorance, wanting the Emeralds for himself. When he turned on Haggra, the Drakon stated that she would not have gathered everyone together had she known who the figure was.
As it turned out, the vapours were incorrect; Sonic did not directly lead the Drakons to the Emeralds. Instead, Grimer pretended to defect from Doctor Robotnik's side and led them straight to the Emerald Chamber.
