For those who want additional inspiration. Here are some angles to work with for "Glyph Forty-Three on Plaque Twelve of the Third Chamber of the Sacred Archives of Oyxl" based on the last word, Oyxl.
Oyxl officially in GW canon is an occupied ruined temple city, but there is relatively little official fluff. It is called the Eternal City. Rome is also called the Eternal City. It may be a fun idea to link Oxyl indirectly to real world Rome or fictionalized portrayals of Rome. Or maybe since there is a quasi-religious focus to this theme, on the Vatican.
Oyxl is located pretty far south where the jungle gives way to the Culchan plains where some Skinks ride on the backs of flightless predatory birds called Culchans, possibly based on these guys.
Besides the presence of these birds, we know very little about the Argentina of Lustria.
The Culchan Plains has some landmarks with no official fluff but very intriguing names. Check out page 25 of the 8th edition Lizardmen book.
Lustria's second southern most swamp is called the Fire Bogs. Legends say there are Skaven Of Unusual Size there, but
I do not think they exist.
The Fire Bogs border a "miscellaneous" (ie not Lizardmen location) called the Hissing God. Spooky!
The Swirling Swamps is where the Culchan plains meet the sea, so it's probably salty and maybe involves whirlpools.
In the jungle part, east of the Oxyl you have geomnatically linked monuments called the Sky Roads. That sounds impressive.
South of Oxyl at the intersection of jungle, mountain and plains you have the Crater Valleys. That sounds like an epic place for rival forces to clash if I ever heard one.
North of the Crater valleys where the jungle meets the mountains is "The Lost Valley." Who or what was lost here?
At the very tip of the mountains (or possible hills because they get smaller) at the southern edge of the Culchan Plains is a chain of four monuments called the Southern Sentinels. Mystic statues? Sleeping gods? Actual Lizardmen sentinels standing guard?
Most of the smaller jungles in Lustria have menacing names, north of the Sky Roads is the Headhunter's Jungle. That's got to have a story behind it right. North of that is a series of large odd shaped forest clearings called the Marks of the Old Ones. That's go to have a story too.
