JL, in this letter Praxiteles announces that he is relocating to Koblenz. Is that pure coincidence that he selected that city? Because the only thing Petronius mentioned to Praxiteles about potential locations was "in the Rhine River Gorge" (in this letter). The only letter where Petronius mentions Koblenz is in a letter to Aedituus, but you may have thought this was sent to Praxiteles (only the title of the post indicated that this was being sent to Aedituus -- I'll make sure any future letter are clearly identified).
If this was indeed a mistake, feel free to change your letter.
BTW, to all, I am updating the first post of the Pre-Saga Correspondence thread to indicate the detailed timeline. It will make interactions easier to track.
