- Main article: War of the Lions
In S.947, Albert was plunged into a war with the other sons of Valius Reise Arnor V over his succession.
Although considered a brilliant strategist, Albert Reise Arnor's army was no match for the Palatinate Knight his half-brother Prince Lucius had just acquired. With the remnants of his private army, Albert decided to join forces with the remains of his half brother Prince Gunnar's army to oppose the other princes. Their force was so large it should compensate for their lack of a Divine Knight.
Over time, he and Gunnar gained control over Magic Knights. With their power, Albert managed to hold off his half-brothers for a number of years. When the Vermillion Apocalypse, however, emerged in Heimdallr alongside the Infernal Castle in S.952, the armies of both Albert and Gunnar were completely annihilated.
