Harry still isn't particularly good at veils 10 years later (or however long it's been).
It sounds like some extremely finnicky magic.
Also, the way things were described was that Marcone did "translocation". Harry belaboured the point a bit, talking about how it was bordering on forbidden, and extremely dangerous. Drakul's teleportation, however, wasn't dwelled upon.
I don't think you can say it was a matter of urgency in the prose. They were both life and death situations, with the fight against the Titan certainly more crucial.
Another one mentioned was Mab's. When Corb tosses the head of the Gwynn ap Nudd to Mab, tantmount to a declaration of war on the Accorded Nations by itself, and insults her, Harry describes her movement. She sort of just appears in front of Corb without passing the space in between. This sounds more like Drakul's movement - sufficiently powerful beings sound like they can simply will themselves about the place. Just as Ferrovax or Odin smush Harry to the ground with pure will, they seem to have reality warping powers that allow them to teleport around the place.
I wonder if it'll be a bit like Harry's "Be" spell, where he manifests in Ghost Story. It won't be a new skill, so much as a set piece spell he uses to accomplish a particular goal. It will involve a huge amount of risk, or he won't be very good at it.
Him reappearing without his clothes on, or inside his wedding cake, would be very much on brand.
