Winterfell’s declaration of neutrality was challenged sometime late Thursday or early Friday when its most powerful military ship was attacked and partially sunk in its home waters.

The Battle Star was heavily damaged in the surprising and daring attack as it was anchored in the Eventtide region of Winterfell. The Battle Star is the flagship of the realm’s High Seas Squadron.

In a statement, the commander of Winterfell’s navy, Adm. Wildstar Beaumont said, “This was an unprovoked attack. The ship was peacefully moored and was showing the Winterfell national flag and not the battle ensign.” The admiral said engineers have recovered the hull and sent it to dry dock for repairs which will take several weeks.
