When William Lovie III. became the king of Lucerne and following the diplomatic fallout of the meeting in the Port of Stormwind it was the decision of the Freys that neutral parties needed to be removed near them or else the Lucernians were going to take them over and give them more of a power base near them. The largest of the neutrals near the Empire of Frey was the Kingdom of Aran that was based north of them on the island of Radin.
