Charles Curling

Lt. Colonel Dr. Charles Curling is the scientist in command of the United States Chemical Corps in 2242.

Background
Curling is a very tired looking man who wears a chemical-stained lab-coat. Stationed on the Enclave Oil Rig off the coast of San Francisco, it is Curling's job to implement the Project to reclaim the world through total genocide. As part of the plan to reclaim both the mainland United States as well as the rest of the world, Curling was tasked with finding a way to modify the Forced Evolutionary Virus into a targeted killing machine. Using samples mined from the Mariposa Military Base excavation, Curling set about editing the virus.

Curling's efforts were ultimately successful, giving rise to FEV Curling-13, Enclave's modified strain. However, evil sprung from evil. The new virus is no longer a vehicle of mutation but a lethal airborne toxin. Released into the jet stream, the virus would be carried worldwide, striking down anybody unfortunate enough to contract it. Curling's efforts were a success of such magnitude that he was explicitly mentioned in Richardson's State of the Nation address.

Aside from creating the virus, Curling and his staff worked on some FEV-infected subjects, including Frank Horrigan, an Enclave soldier who was stationed on Mariposa before he got infected. The modified FEV development was not the single result of these experiments, as Frank Horrigan was soon made into the ultimate killing machine and the Enclave's finest tool of warfare.

Naturally, the only way to employ such a weapon would be to have a safeguard against it. To that end, Curling and his team also perfected a vaccination against the modified FEV. Once the vaccine was distributed to Enclave forces, the eradication program was to be set in motion. By the time the Chosen One boards the oil rig, the Enclave is days from releasing the virus.

In one way or another, Curling met his end on the oil rig during the final events of Fallout 2. Whether killed by the Chosen One's hand or when the rig exploded, Curling was removed from history and his efforts removed with him. With the rig's explosion, Curling's legacy of a deadly form of FEV was erased and never noted following the rig's destruction. As far as the dwellers of the wasteland were concerned, Curling never existed.

Quests

 * Stop the Enclave: With a high Speech and Charisma, Curling can be persuaded to rethink his mission and abandon the Enclave, thus making it impossible to release the FEV.

Other interactions

 * Luckily, Lt. Col. Curling does have a conscience, somewhat dormant though it may have been. On some level, the idea of exterminating hundreds of thousands of very-near-humans doesn't sit well with the good doctor, and despite his dogged pursuit of his mission goals, he is not a zealous follower of Dick Richardson's plans.
 * This presents the Chosen One with an option for averting global catastrophe. While Curling can be easily ignored - or almost as easily eliminated - having a high Speech and Charisma can make Curling rethink his mission and abandon the Enclave. Swayed by persuasive argument, Curling will choose to inoculate the Chosen One with the antivirus (as well as the Arroyo villagers and Vault 13 residents) and release the modified FEV into the Oil Rig's sealed environmental system instead of the outside world.
 * While the virus will be filtered out by certain equipment such as power armor helmets, any non-military personnel would nearly immediately succumb to the effects, creating a diversion for activating a countdown on a nuclear self-destruct to neutralize the virus threat (seeing that Sergeant Granite and his men are unaware that a self-destruct is in progress until the Chosen One informs them).

Appearances
Charles Curling appears only in Fallout 2.

Behind the scenes
The poem Curling recites when convinced of the horrific nature of his actions is William Blake's The Tyger.
