Dear Elder Flynn, of the Eternal Dominion of the Crab,

How odd, that you should see a blank letter where there is a wealth of information. Perhaps your kind is simply not sufficiently in tune with the multilayered and multidimensional intricacies of language. I assure you that Al'Daric is very, very real and that this is not a prank - though the great philosopher Iocus once argued that the entire universe is a prank on a cosmic scale. Later scholars mostly disagree with his theory, though none have been able to provide absolutely conclusive evidence to the contrary yet.

As for the number 42, that is shorthand for my full name, 2075235907148065388063602961473671194026324051631622913300336126313878864067241229288498692169645696328859008758253380698689283016021136690902123819975898071500332347981367052144389103020314396516838074666554529448638070280666940988806680675256244887909174345728. Much to my initial chagrin, I came to understand that some people find this too unwieldy for their taste, so I now also answer to the moniker of 42. 

It is interesting that you have found reality near Dun Sancerre. I had not learned of the existence of a particularly *real* section of this world prior to our correspondence. Perhaps my archives are incomplete.

To answer your query about immortality, the inherent difficulties of using magic to achieve any semblance of permanent life are well established in a wide range of texts by reputable authors, chief among them being A Brief History of Time by Sesquipedalis the Verbose and The Prime Principles of Perpetuity by Jhon Johan Jayhan the August Arch-Alliterator.

Perhaps you could tell me more about yourself and the Eternal Dominion of the Crab? I fear that I do not know much about you or your people. More context could help me direct you in your quest to understand more about magic's relationship with eternity.

Best regards,
2075235907148065388063602961473671194026324051631622913300336126313878864067241229288498692169645696328859008758253380698689283016021136690902123819975898071500332347981367052144389103020314396516838074666554529448638070280666940988806680675256244887909174345728
