Gen Whitelaw, born Gen Almodovar, is a Shadowhunter—one of the first few to Ascend again after decades. Gen was among the first batch of students at the reopened Shadowhunter Academy and trained alongside other Shadowhunters and mundanes, including Simon Lewis.


In 2008, Gen was recruited into the Shadowhunter Academy for potential Ascension. After two years of training, Gen and nine other mundanes were set to finally go through Ascension—a ritual with known risks. Gen was called first as they were arranged alphabetically. After some ceremonial rites and swearing to uphold the oath dictated by the Consul, Gen drank from the Mortal Cup and survived, successfully Ascending into a full-fledged Nephilim.[1] Gen took on the Whitelaw name.

Gen went on to become a Centurion, alongside fellow Academy graduates Jon Cartwright and Thomas Aldertree. The three of them went on a mission in Los Angeles in 2012.[2]


  • In Lord of Shadows, Gen was first referred to as Gen Whitelaw and then later Gen Aldertree, likely a mistake as fellow Ascendant Thomas took the name Aldertree.
