Atlan is the Messenger of the Gods.
Messenger of the Gods
This term can be open to misinterpretation and so some clarification is needed. Atlan is not an errand boy or servant of the Gods. He is actually considered to be one of the Greater Gods. The term messenger in this instance is more akin to emissary. For Atlan represents the Gods on matters of great importance and is entrusted with the conveyance of the consensus of the Greater Gods to mortals and Gods alike. His powers of communication are unrivalled.
He is seen by some scholars to be a son of Hydana and Throff. This combination of parentage is thought to be symbolic of his ease of travel over both land and water.
The patron of travellers, Fulkra, and the patron of mariners, Solinthar, are the sons of Atlan.Template:Non-canon
Some scholars argue that Atlan himself is the Sounder of the Final Horn, depicted in the Southern Skies of Titan.
It is also very possible that he has also gone by the name of Jack-in-the-Green.
'Jack-in-the-Green' is an entity that, on rare occasions, has been seen by noble heroes and has acted as a messenger for Titan. The fact that this seems to overlap with Atlan's domain leads to the belief that Jack-in-the-Green is the name given to Atlan in some parts of the Old World.
He is said to have referred to the fact that he also known as the Ancient King. Given that Atlantis was named after Atlan and at the heart of this lost island was Mount Atlan[Titan] the volcano it is possible that Atlan first held the mantle as guardian of the realm. The people of Atlantis regarded their king as a direct descendant of Atlan. It is therefore logical to presume that he was seen as the first king of Atlantis. Hence the Ancient King.
