Captain's log, stardate 3211.7 
We are entering standard orbit about Gamma II, an uninhabited planetoid with an automatic communications and astrogation station. Ensign Chekov, Lieutenant Uhura, and I will beam down and make a routine check of its facilities.
Captain's log, stardate 3211.8 
While beaming down from the Enterprise to inspect facilities on Gamma II, the normal transporter sequence has been interrupted, and we find ourselves on a strange and hostile planet, surrounded by creatures belonging to races scattered all through the galaxy.
Captain's log, stardate 3212.2 
First Officer Spock in command. The captain, Lieutenant Uhura, and Ensign Chekov have been missing for nearly two hours. Computer probability projections are useless due to insufficient data.
Captain's log, supplemental. Stardate… unknown 
Our strange captivity continues. This planet is called Triskelion. We do not know its location. We do not know who controls it. Its dangers… are abundantly clear.
