The Isles of Logic are an island chain likely somewhere within or near Enchanted Isles (KQGS) and Green Isles (KQGS) in or near Neptune's Kingdom (KQGS).
Background[]
The Isles are the location of the Academy where Vee (KQGS) attended on scholarship, and held all the records. It is probably not to be confused with the northern Knight School (KQGS) Graham attended (which he also refers to as 'the academy').
This is the home of the winged ones (KQGS) in the Green Isles (KQGS). Graham (KQGS) once had a sorcery battle with the winged ones. Winged ones may teach at The Academy] on the islands.
Behind the scenes[]
This maybe a reference to the Green Isles and more specifically Isle of the Sacred Mountain which known for its Cliffs of Logic. The Green Isles (KQGS) is the homeland of Cassima (KQGS).
