I actually did find something, but forgot to add it: The cell to the northwest of Old Uskasarak is called 'PaladinCastle' so that would probably be the former location of the castle. On the screenshot it would be somewhere in these dense clouds above Ark, which could explain why it is not visible.

Part 8: "Brave Old World, Part I" Today we are going to look back at the very beginning of the order: A time where "The Holy Order" was still called "The Paladin Order" and didn't reside in the suntemple but the paladin fortress. The first concept arts of the suntemple were posted in 2013, so one c...

Guck vielleicht mal auf seiner Patreon-Seite vorbei, er postet da ab und zu einige öffentliche Updates unter anderem zu einem Buch und einer "Episodic Novel" über Jespar, die er gerade schreibt

Ja sieht schon sehr beeindruckend aus so, aber außer dem Eingangsbereich besteht sie anscheinend nur aus Fassade und wenn ich mir überlege wie die Performance im Spiel in der Stadt ist, dann will ich wirklich nicht wissen, wie sie hier wäre, wenn man die Stadt mit mehr Details spickt.

Kapitel 9: "Handbuch der Trailer und Visionen" Kleine Spoiler für die Story Enderals! Erinnert ihr euch noch an die ersten Videos und Teaser zu Enderal?

Part 6: "The Fist From The Water" Somewhere on Enderal in the middle of the Powder Desert, there is an isolated crater containing an apparently inhabited oasis, probably called "The Glass Fist" or the "Palm-Tree-Refuge". Around the water there are some smaller huts, mostly built on stilts and parti...

Kapitel 8: "Schöne alte Welt, Teil I" Heute begeben wir uns ganz an die Anfänge des Ordens zurück, in eine Zeit in der der "heilige Orden der Hüter" noch der "Paladinorden" war und nicht im Sonnentempel sondern in der Paladinfestung residierte. Die ersten Concept Arts zum Sonnentempel sind von 2013...

Yeah there is a lot of randomly floating stuff in that cell. Apparently this dungeon as well as a few others (judging by the CellIDs) were made by a level designer, that left the project at some point. While they do look pretty cool, none of them is finished and some of them are rather messy with a ...

I think he might be referring to "Myths and Legends Volume 4: The Mountain in the Desert". I don't think the exact location is described in the book, but the mountain is somewhere west of Duneville close to Priest Tolgans House:
