The career of Guy Servais (Raives, an anagram of his name) is closely tied to Éric Warnauts. Their collaboration started when Warnauts wrote two volumes of 'Paris-Perdu', that were illustrated by Raives in 1985 and 1986. Afterwards, Raives and Warnauts continued their joint oeuvre, both doing artwork and scenarios. They started out this line of work with the series 'Lou Cale' (Ed. du Miroir), followed by several stories for À Suivre ('Congo 40', 'L'Envers des Rêves', 'Lettres d'Outremer'). For Casterman, they created 'Les Suites Vénitiennes' in 1996, followed by 'Un Diamant sous la Lune' in 2002-03. In 1999, Raives and Warnauts teamed up with scenarist Michel Vandam to produce 'Kin' la Belle'. In 2000 they were present at Glénat with 'L'Orfèvre'. Raives is also a colorist, among others on Jean-Claude Servais' 'La Mémoire des Arbres'. Despite sharing the same last name, Guy Servais (Raives) and Jean-Claude Servais are not related.
Raives was one of several artists to make drawings for the "safe sex" promotional book 'Les Aventures de Latex' (FortMedia, 1991).
