Keeps track of people

His head tipped me a tiny nod, and then he turned to beckon the others. Wardens and Senior Council members began clambering out of the boat. I walked down the dock beside Ebenezar, watching the Wardens over my shoulder. They were the sort of men and women who had no illusions about violence, magical or otherwise. If they decided that the best way to deal with me would be to shoot me in the back, they wouldn't hesitate.
I stepped off the dock and onto the island again, and immediately felt the presence of Demonreach. At the moment, the only persons on the island were those I had brought with me.
Ebenezar followed me, and I felt it the instant he stepped onto the shore. It wasn't as if someone had whispered in my ear. I simply knew, felt it, the way you know it when an ant is crawling across your arm. He stopped a step later, and I kept going until I was about ten feet away. I turned to face them as their group came down the dock to stand on the shore. I kept close track of them through the link with the island, making sure that there weren't any Wardens hiding behind veils so that they could sneak up behind me and start delivering rabbit punches.
