This King puzzles me because he is obviously a scholar and he also looks a bit like a magician. But where is the feeling and emotion? Is it represented by the sea behind him?
All the other suits/elements seem to be present here: there is a wand and the wind is blowing hard (air, swords). The books are the material side (as in pentacles) and the seawater could represent the feeling just as the chalice in front of him.
Is he dropping something in the chalice? It looks like a pearl. Or maybe it is rising from the chalice.
The LWB says his "wisdom and experience keep him away from the dangers and risks of love" That does not sound like the traditional King of Chalices who I think would be quite an expert in the challenges of love.
