| Year | Major Event |
| Humans, dwarves, and elves evolve and start forming their respective communities. The humans settle around the shore of the peninsula, the dwarves in the mountains, and the elves across the sea |
| The human cities Tor'Dagar and Yosh'Gallian grow prominent along the opposite shores |
| After a century of tension between the two cities, Tor'Dagar is pillaged and ruined by Yosh'Gallians warriors; the city is burned and the survivors taken as prisoners |
| Jarvek Al'Thaden is born, a distant cousin to the throne |
| With no heir to the throne, civil discontent rises as the monarchs die |
| Jarvek seizes the throne with his word and sword, having successfully gathered enough followers for himself. He changes Yosh'Gallian to Arithmere, and names it the capital of his new nation Al'Thania |
| Jarvek Al'Thaden dies at the age of 75, having created a peaceful city with bolstering trade. Mathis, his second son, ascends the throne |
| Mathis dies, having led a peaceful but prosperous city. His grandson Markus is made King |
| Markus, with the help of the dwarves, forges a permanent pass through the mountains to the mainland, helping traders travel without being raided by orc bandits. He builds a fortress on the mainland to help maintain the integrity of the pass. |
| The nation's 100th anniversary is marked by Markus's vast expansion using stone walls to protect his people from the growing population of orcs |
| After a great storm, a foreign sea vessel arrives, the crew speaking of their home wonders on distant waters. Markus welcomes them to his city and ascents to their trade goods. They return every few years, but guard the secret of their route jealously |
| At age 71, Markus, deemed Markus the Great, dies, leaving his son Corin to reign |
| Corin is assassinated by a mysterious assailant, and Viktor ascends the throne |
| A sea wall is built around the port of Arithmere, to protect the harbour from both the harsh winds and the occasional pirate raid |
| The elves, secluded from the rest of the world in Nathul’Fairn Shyr are driven out of their home by one of their own kind. They scatter, and some come by sea to Arithmere, seeking refuge under the startled humans who have only heard legends of their race |
| Niklas, Viktor's son, takes the crown from his late father |
| The second century of Arithmere is celebrated by the elevation of Jarvek's and Markus' statues in the city square |
| Niklas's only son goes on a year long tour with his entourage to view the outlying villages, and then towards the mountain pass to the fortress |
| A trembling of the earth sets off an enormous avalanche, which effectively destroys the entire pass. Communication with the Prince's entourage is stopped, and his grandson is forced to represent the throne |
| After two years of being unable to communicate or trade to the mainland without expending massive resources on sea fare, Arithmere is forced to rely on local resources, and Tommi declares his father dead, thus securing the crown |
| With food and resources being scarcer, the problem of orc bandits increase and Tommi evokes a heavy bounty for all orc heads |
| The king dies in his sleep, and his son Aaron is pronounced king |
| The Black Plague begins to spread through the lower ranks of society, and passes on eventually to the nobility and royalty. A great many die, including King Aaron. Azreal also succumbs to it, but recovers and takes the throne |
| With the recovery from the Plague and continued strained communication to the mainland by sea, Azreal decides to head an expedition to the mainland and the fortress, despite warnings of his health from his councillors |
| Azreal takes his expedition on water, and travels towards the mountain fortress. Upon arrival the expedition is attacked by goblins. Azreal is killed, and the survivors flee, some back to the boats, and others into the woods |
| With the tattered expedition's return, Jani Al'Thaden, Azreal's younger brother, is forced to take the throne |
| The fourth century of Al'Thania commences, witnessing the recovery of both the Plague and the Azreal's death. The city prospers again, though without the aid of the north. |
