The current active CoRE gm's are: Henry winter (brigands of the Fort), Vierna (Floh'len d'Lloth (drow)), Irvyn (Duchy of Trinsic) & Devante (Stirling & Kendall trading company), Gwen Irima (The Elven Guild). You can probably pm any of these with any questions
But for questions about overall state of rp you can ask anyone on this forum. There are more guilds out there then just the CoRE guilds.
