Kthanid

Description
Kthanid is an Elder God and said to be the brother of Cthulhu. A member of Cthulhu's race, he helped banish his brother and the other Great Old Ones to Earth before binding them.

He looks exactly like his sibling, the only difference being his peaceful, golden eyes. He bears a great hatred for The Great Old Ones for they had killed his family while he lay sleeping.

Despite his immense power, he is not capable of actual violence and only uses binding spells or memory-erasure to deal with his enemies. Kthanid is supposedly responsible for the fact Great Old Ones fear the Elder Sign as he placed a fear of it in the back of their subconscious.

As a Deity
Kthanid is known for his benevolence and knowledge of the Great Old Ones and often grants boons of knowledge to those that are able to summon him through the use of the Necronomicon. These boons are useful for those trying to avoid the influence from powerful beings.

Religions and Cults
Due to his secretive nature, there're no known cults or religions dedicated to Kthanid. However, those extremely few who have been granted boons and blessings by Kthanid often form small esoteric covens dedicated to the benevolent deity.
