The second image above (hand drawn) shows that "A Keeper's Training" is located at the "Keeper Compound".
This is assumed to be part of the same compound from Thief:DS and would be attached to that map.
The colored map alignment is based on its orientation in Dromed and the in-game compass.(up is north)
The Keeper Compound & Lower Libraries is where Garretts trial was referenced here and is also named in these two files KeeperCompound.jpg KeeperCompoundLowerLibraries.jpg as well as on the TDS Old Quarter map
