Lang "BlizzEgo" Gwydd is a pre-made Sim who lives in Twinbrook from The Sims 3: Ambitions. He lives with his roommates Justin Kayes and Wei Keane, who all have the Computer Whiz trait. Their household, Hi-Tech Friends household, resides at 332 Rue de Sterling in Greek Revival. His name is a pun of "languid", which also matches his personality.
Despite the fact that he starts with no skill when first played, he actually has high hidden skills; level 3 in Video Game, level 7 in Hacking, and level 3 in Chess. He has the highest Hacking skill between his roommates. Lang is a fat Couch Potato who Hates the Outdoors. It's implied that he plays the video game in his room everyday, which makes bad impression to his job. He works as a Decoy in Criminal career, but his performance is very low, which is 50% towards the bottom. If he doesn't improve his performance, he might eventually be fired. However, his lifetime wish is to work in Ghost Hunter career, which means it's better for him to leave his job and start in this profession.
Lang is friends with Justin, but acquaintances with Wei. Their relationship is too poor to be friends, but not negative. He is friends with his neighbor, Anna-Liza Riddle, and enemies with their other neighbors, Bobby and Scout Sargeant. Oddly, Wei is friends with the Sargeants and enemies with Anna-Liza. Lang is also romantically involved with Dilly Pidgin. She, however, has a large age gap with Lang. She is in the middle-end of her adulthood, while Lang is in the early of his age in young adult.
