Just a random map from Arcane Dimensions, which I note, has also been recently updated to v.1.7 (though I believe the changes are relatively minor, at least compared to previous versions). As always, I would like to thank Simon O'Callaghan and Vondur for their work (and indeed anyone else involved in the creation of Arcane Dimensions, and for the modding of Quake in general).
