Gruthar

Gruthar is the mighty leader of the intelligent deathclaws of Vault 13 in 2241.

Background
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 on their unknowing neighbors. Despite being bred by the Enclave, he harbored disdain for them and has to cope with his conscience, as he takes full 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.

Interactions with the player character
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.
 * Have a low intelligence.

He will also ask for his assistance (if the player doesn't have a low intelligence) with the mainframe running the Vault, sabotaged by Matt. In return, he will give the player character the G.E.C.K. he was looking for, unless it was already looted by him/her.

Unfortunately, this also 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.

Appearances
Gruthar appears only in Fallout 2.
