After the nuptial festivities, Sir Anduin Lothar asked Lord Corlys Velaryon for permission to marry his daughter. The Sea Serpent was initially reluctant to give his daughter's hand to a foreign knight. Some speculated that the Lord of Driftmark wanted to marry Laene to the rogue prince Daemon Targaryen. However, after strenuous requests from his daughter Laena, Velaryon agreed to the union. A few months after the ceremony, the couple married. The couple divided their time between Azeroth and Westeros. After the birth of the children, Anduin was offered a permanent presence in King's Landing as Stormwind's ambassador and military consultant, to which he agreed. People say that this was prompted by the persuasions of Sir Anduin's good friend Prince Muradin Bronzebeard and Queen Alicent, with whom he managed to become friends. He also sent his representation to Lord Admiral Kul Tiras in the form of his younger son Tandred Proudmoore, and to Queen Alicent for the temporary upbringing of Lady Jaina Proudmoore's only daughter. Following the death of Lyman Bessbery and the assumption of his position by the former senior over the ships Sir Tyland Lannister, Lord Corlys Velaryon was called back into the position, to which he agreed
Prince Daemon Targaryen flew to Essos after the nuptials of Princess Rhaenyra Targaryen to Sir Laenor Velaryon for several years. During this time he managed to marry the daughter of one of the great magisters. Unfortunately, his wife died in childbirth with their first child. The next day Prince Daemon flew out of Pentos to Westeros. Princess Rhaenyra had by this time given birth to two sons with brown hair and eyes. Many speculated that the father of the two was Sir Harwin Strong, who, along with his father, died moments before Prince Daemon arrived at court. Nine months later, Princess Rhaenyra gave birth to her third child who was completely different from her two siblings. It had pristine white skin and Valyrian hair and eyes, and a few years later another with the same features. Most identified the paternity of Princess Rhaenyra's two youngest children in the person of Prince Daemon. The king forbade the spread of this information under threat of having his tongue pulled out, which only resulted in the rumors increasing rather than stopping - Arcymaester Gyldayn,Fire and Blood, Being a History of the Targaryen Kings of Westeros
When the people of Azeroth began trading with their sister continent they encountered one major problem - banditry. Unlike Azeroth, Westeros was full of mercenaries and highwaymen. To overcome the problem, the Covenant forces had to be engaged. After some time, bandits stopped harassing convoys carrying the symbol of Stormwind or Ironforge
An important development was undoubtedly the willingness of the Essos rulers to open trade directly with the Covenant. In doing so, they offered Stormwind a piece of land in Essos so that the Alliance could ship its goods without intermediaries. Up to that point, the land had been offered south of Tyrosh. The fortress of Valiant was built there. When merchants began setting up store outside the fortress they became targets for invaders. It came to a climax when a huge Dothraki army led by khal Baaro arrived at the fortress to plunder it. High general Lothar at the head of the covenant forces repulsed the Dothraki army by personally killing the Khal in a one-on-one battle. After this victory, merchantry began to explode outside the fortress in a big way, multiplying the profit that was going to Azeroth.
