Utterly Mad

Why did you become Red?

Short answer is that Red is an easier shorthand then Vulnus.

Long answer is that I got tired of having people purposefully mispronounce Vulnus to annoy me and after playing Project Reality as RedVulnus I found Red a good shorthand since you could just shout 'Red watch X' over voip so I'd hear that instead of 'Vul-Vil? Whatever the fuck your name is watch X'. Evidently Vulnus sounds like Vilnis to a lot of people.
