@ilinx:~$ Letters Vysparov-Stillwell
The corrispondency between Echidna Stillwell and Peter Vysparov is extremely relevant because it is considered the first step to the creation of the Miskatonic Virtual University. Recently the MVU press released a digital copy of the original letters, otherwise, another version of the same letters can be found in Ccru's texts as Origins of the Cthulhu Club
