I am going to compile a list of active Medusan Lords. I will separate this list into official MLs and Player Run MLs. If anyone knows of a ML that I need to add to this list please make me aware of it and I will add it. If an ML is NOT on this list it has either been defeated or has been retired. All MLs are 4E challenges unless officially stated otherwise.

Current Official
Alex Venator - Malexin
Albrecht Hive Mind - Malexin
Orvac Granitefall - NirvanaTool
Caitlyn the Free Hive Mind - Hedge (ancients or 4E)
Gixu - AshGaiden
Gixu - Iceman
Gixu - DadofDavid
Gixu - Maverrick77

Current Player Ran
Archos Loth - NirvanaTool
Eiael Darkfeather - nilonka
The Terror of Ithan Spire - Kerebrus


Edit: This means that the following undefeated MLs are retired: Taliesin, Fasolt Hivemind, Jodin Drac Hivemind, Nitesh Imaran Hivemind, Barruk and Lady al-Semmeya, Sedara Tansiq, Gwyrneth-Ra, Far'um'Far, Atu the poisoned field, Legion and the fifth copy of Archos Loth. This is confirmed and can be considered official.

Edit 2: The copy of Archos Loth run by NirvanaTool is the considered to by copy #1. Copy #2 through #4 were also defeated. Copy #5 was officially retired. Zechnophobe said he was going to send Copy #5 of Archos Loth to Brazil however there has been no conformation as to whether it was received in Brazil as there has not been an event in Brazil where challenges were taken.

Edit 3: just_porter won the raffle to become a runner for Gixu. He has not taken any challenges yet and as such will be listed but be advised that he may not have a copy of the ML yet to take challenges with.

Edit 4: Hedge's Gixu removed from list following defeat on 7-17-2010.

Edit 5: Updated to remove Kerebrus' Gixu & change Eiael's runner. Also removing just_porter's Gixu as there has been no confirmation that he received it or intends to run it.
