...Heirs of Alexandria are a thing...where essentially magic was discovered in the Library of Alexandria...

...Temeraire Series, where Dragons exist in a rather accurate alternative history of the Napoleonic War, and are as big as ships (with crews and black powder).

...Oh! If you are okay with Mercedes Lackey style works, there's the Dragon Jousters! Sort of a reimagining of Atlantis and Egypt where there are Egyptian-style gods, avatars, (dragons, of course), and soul-magic able to control nature.

...Or the Sovereign Stone Trilogy...which essentially has ent-hobbits, undead magic, avatar magic, elemental dragons, Warpspawn, dwarf horsemen, and a nation of sailing Orcs.

...Not sure about Acorna's World or the Elvenbane series...the former is Anne McCathy (who like George Orwell can be a tad...off at times) and the latter has Author Existence Failure (she died on the third/fourth book)
