I've prepared a draft map for Mnemosyne so we can all run it a bit easier in the future. The mobs are huge and are all no stab, but there is surely eq in this zone that has never been loaded.
https://ibb.co/6BK582HThe area can be tracked to through The Kingdom of Luilekkerland on AH, or by tracking poet-tom. Unfortunately the main entrance to the area requires a prime bard to sing "knights blessing" however there are a few ways around this... you can try "ambush tom" or you can create a new sloth character, ptest bard and sing 'knights blessing' to open the door and then login your main.
There is one door (Room 41) that it appears that no one has ever figured out the trig trap to. I've talked to a few players, emailed some more... and gotten logs from some others, and it would appear it's never been figured out. Feel free to post your theories in here, or tell us if you know. If it's not a trig trap to enter, maybe a key loads somewhere... perhaps the bunyip mob.
It would appear there should be 10 "goddess" mobs... It would appear only Calliope, Erato and Euterpe have been loaded.
