... reading Mordenkainen Tome of Foes, where the latest githyanki lore is told, I'm glad to see Larian just follows the lore given by someone else without trying to twist it for any reason...
I personally feel that there's a lot of vanilla D&D lore that could use some twisting.
My biggest misgiving about BG:3s story was how much they've said it ties in to Descent into Avernus which was a bit underwhelming.
