It takes a couple of minutes for Caesar to get things online, and another minute to alter the settings to open a little away from the area that Zaknafein had been in. Not that it's 100% accurate anyway in terms of location, as the calibration is only an initial and not a more precise one, but it'll be enough. Caesar waits for it to detect an open area, and then he smiles.

He gives Zaknafein a thumbs up before pointing at the still closed portal. "Ready?"

... Okay, he's holding the dead elf by the arm. Caesar's pretty sure he means to throw the body if there's something on the other side when the portal opens, but that doesn't stop it from being creepy.
