Tondc

Tondc is a location on Earth featured in the second season. Much like before the nuclear war, Tondc is a political key location for The Woods Clan.

History
Before the nuclear war, Tondc was Washington DC, the capital of the United States. Almost 100 years later, it is inhabited by Grounders. It appears to have maintained its political importance, since it was the place where Lexa had brought all twelve Grounder Clans together to form an alliance in Rubicon. It was destroyed by the a missile sent directly from Mount Weather in that same episode.

Throughout The Series

 * -|Season Two =

In Human Trials, Finn Collins and John Murphy were sent to Tondc to investigate where the Delinquents where. Finn and Murphy come across several grounders, and pin them all in a small pen to get answers from them. Finn scatters the camp but finds nothing while Murphy guards the grounders. Finn comes across several jackets worn by the delinquents, and asks the grounder where their friends are. Murphy tells him that there is nothing to worry about, but Finn disagrees. When it is revealed that the grounder Delano gave Finn this info, a grounder named Nyko steps in to tell Finn that Delano spoke lies and only wanted revenge because he was cast out. When Finn and Murphy leave however, one grounder tries to leave forcing Finn to shoot him down. This causes and onslaught of grounders to attack Finn, causing him to kill 17 more grounders in the process.

In Remember Me, Finn's dead body in burned in Tondc as a death ritual for the grounders. After he is burned, the Sky People and grounder make peace with each other. However, a grounder named Gustus tries to poison himself as a way to trick the grounders in to believing that they are enemies. When it is revealed Gustus was the one who poisoned himself, Lexa the commander kills him for his treason.

In Rubicon, Lexa has brought together the twelve Grounder Clans in order to make peace with their people. Clarke Griffin however has info that a missile from Mount Weather is scheduled to destroy all of Tondc. Lexa says they must leave alone to make sure Bellamy Blake's cover at Mount Weather is exposed. After many arguments, Clarke agrees to leave with Lexa, and Tondc is bombed, killing hundreds.

In Resurrection, the grounders are seen recovering from the massive explosion sent from Mount Weather. Over 150 grounders died in the bombing. Even after the bombing, there is a sniper who gave the signal to the Mountain Men to shoot the missile. The sniper picks off grounders one by one, but is ultimately thwarted by Clarke, Lexa, and Lincoln. After the sniper is taken care of the Sky People go to aid the grounders in the destruction of Tondc. Later Lexa gives a speech to all of her fellow grounders that everyone will be avenged, and the grounders will prevail.

Trivia

 * Tondc is the first Grounder village seen in the show as it is Lincoln's village. https://twitter.com/the100writers/status/558085495688011778
 * Tondc is built on the ruins of Washington D.C. The name is evidently based on a broken sign, and the Grounders simply assumed that was the full name of the place.
