Most people probably remember this passage towards the end of LWW:

”

But amidst all these rejoicings Aslan himself quietly slipped away. And when the Kings and Queens noticed that he wasn't there they said nothing about it. For Mr Beaver had warned them, "He'll be coming and going," he had said. "One day you'll see him and another you won't. He doesn't like being tied down and of course he has other countries to attend to. It's quite all right. He'll often drop in. Only you mustn't press him. He's wild, you know. Not like a tame lion."

So basically it sounds Aslan would sometimes come for “dinner visits” while the kids were reigning, although Lewis doesn’t really elaborate on that when he goes on to describe the Pevensies’ reign in Narnia.

However, later material makes it seem like at the time of PC, Aslan hadn’t been in Narnia since the events of LWW (his scenes in HHB being set in Calormene and Archenland). I’m kind of disappointed by this, but I’m not sure if it’s even true, it might have just been the implication I got. I do remember reading on a biography section for Aslan that he disappeared out of Narnia for “a number of years”, but perhaps it was simply mistaken. Does anyone know if it was ever confirmed that Aslan never visited Narnia between LWW and PC?
