He barked at Vargas, ‘Turn on the tri-D!’ Vargas stumbled over to his desk and obeyed.

Interest in their home system was at fever pitch. The secretariat had arranged tridi FTL coverage from underneath the transparent track, so that viewers could observe the cell-by-cell approach.
Now—I want a run-through of the Ruhkarv report in comparison with the tridees from Xcothal.
Kosgro switched the three through the air and thrust in and out with them as I had seen swords used in tridee tapes made on primitive worlds.
