There are 3 branches of reasoning for this: - The obvious gold component from all three of Mesa, Gilded, and Wyll’s luck theming - The idea behind rush coming from the wealth gem ability Rich Rush, again tying into Wyll’s luck themes and Alrey being considered to “main” wealth - The meaning of the Gold Rush, “a rush to newly discovered goldfields in pursuit of riches”. While not as clear as the other two, it can certainly be attributed to Wyll in some regards at his betrayal of gilded, and potentially as a mining motif since Alrey literally lives in a giant cave (on the server. In real life he probably lives in a house.)
