Hatonn is the name of a Higher Dimensional Entity, or Ascended Master, who is said to be a member of the Ashtar Command.
Supposedly, he is in charge of stabilizing the etheric Earth Grid. When the Sirians realigned Earth's Grid, it was upon instruction of Hatonn.
Quite some channelers receive his transmissions.
