The 28 year old joined Neath from Neath Athletic Colts and made his debut for Neath back in 2012/13.
His first appearance was as a teenage replacement in a 23-9 win over Swansea and he went on to play 21 games for the Gnoll club and scored 3 tries.
Luc then moved on to a professional and semi-professional career with over 200 games under his belt for the Dragons, Harlequins, London Welsh, Richmond, Jersey and Rosslyn Park.
His return will be a big boost to the Welsh All Blacks who currently lead the WRU Championship and are looking to build on their fine first-half to the season.
Head coach Patrick Horgan said, “Luc will bring a lot to the squad. He has all the attributes needed in a scrum-half and, like his father Lyn, he has rugby footballing instinct and knowledge – backed up by high-level experience.
