I think Midian's set for 5th level. I attuned the spell shard to Call Lightning, and threw in stats for an Ape companion, whom obviously I'm assuming would be showing up when we get to the island, not swimming out into the sea to meet Midian. 
His spell selections are actually made assuming we're moving forward to the island (assuming he'll burn warp woods and mendings the next morning for the masts, but then have a day or so before we make landfall).
Let me know if I missed anything.
