From Unidoom Wiki
infurnus used to play in the IDL circa 2005, has contributed to UDM3 and UDMX (mostly palette edits and testing/feedback), and plays games with UD.
They occasionally work on projects with YEDS (Yeoman Engineers and Designers of Software) and The Jetsons, such as 32in24 and SpaceDM9.
Making music and pixel art are their hobbies, as well as other nerdy video game development things and stuff done in their spare time.
Contrary to old rumors, infurnus is not related to DOOMGUY666, and is not CodeImp or Nightfang.
infurnus may or may not be a furry. (infurnus? more like infurrynus, amirite)
