Well, deathclaws are dangerous by nature and great care must be taken when encountering them in the wild. However, I am certain that you have noticed that we are an exception. My pack poses no threat to you or your human communities. We have evolved beyond our base cousins and wish simply to be left alone.
Gruthar is the mighty leader of the intelligent deathclaws of Vault 13 in 2241.
By far the most impressive and strong among his pack, Gruthar is the alpha male and leader. He possesses an uncanny intellect and a deep life philosophy, respecting human life and trying to minimize the impact he and his pack make upon their unknowing neighbors. Despite being bred by the Enclave forces, he harbored hatred and dislike for them and has to cope with his conscience, as he takes complete responsibility for his pack's part in the abduction of the Vault inhabitants. Goris, a very intelligent albino deathclaw, is his son, privy to his father's doubts and internal struggles. He may be as smart as his father one day.

- Unfortunately, the G.E.C.K. transaction triggers the massacre of Vault 13 inhabitants two weeks after the exchange takes place. There is no way to avert this, short of not talking to Gruthar after fixing the computer.
 Other interactions
Being the leader of the Vault 13 deathclaws, he is the first one to speak to the Chosen One, asking him to not disturb the peace of the Vault. Gruthar may or may not allow the player to enter the vault. To be allowed to enter, the player MUST meet one of the following requiriments:
- Have good karma, in order to convince Gruthar that he/she wishes to help the pack.
