Thale

From The Yellow Site

Thale is two seperate people. Firstly he is one of characters from The King In Yellow. In the texts of James Blish and Lin Carter Thale is the son of the queen Cassilda. It is normally considered that he and his brother Uoht are rivals in love for the hand of their sister Camilla. In other sources the name is attributed to a king who wore The Yellow Sign upon his cloak. It seems likely that one takes their name from the other.

[edit] The Encyclopedia Cthulhiana says...

Under his own name, the Encyclopedia Cthulhu states two alternatives. He may simply be a "character in the play 'The King in Yellow'." However, he is also "according to Hali, the second king to blazon the Yellow Sign upon his cloak." Judging by other sources (such as the entry for Uoht) this should read "the second king of Carcosa".

Under the entry for the play, two alternatives are suggested. Either he is simply one of several claimants to the throne of Yhtill or he is one of two sons of the ruling queen of the city of Hastur, which has been at war with its neighbor Alar for countless years.
