Chronicle Anthologies of Speculum

This is my first story and serves as a prequel to another story I have in the works (the temp title of it is in ch 1) that shares the same Nation summoning theme as Nihonkoku Shouken. This story serves as a large supplement to the lore of Speculum (My original world) with the first volume being so far the only link to GATE itself. Volume 1 is about the Empire of Trebizond in 1460.
