A long time ago, on a forum far, far away...
Marco - Maltheus is one of the old ones. Back when Inquisitor was still on the OLD GW forums (circa, I think, 2002, as I'd just gone to university), that's when ArbitratorBob, Saussure, Nexus, Charax, NO1-H3R3, Maltheus, me under my old handle SlaaneshBen, Mentirius, InquisitorRex, Mefisto, Espen / Drazh, Xaras, and a host of others first got things rolling. Then we moved to the Specialist Games forum, wow, some time around 2003. After that, we RP'd heavily, some of which has been saved, most has been lost.
Fast forward to 2013, and there's a revival - part spontaneous, part poked; part coincidence, part providence.
