Arbelough was the site of a battle at which Bashar Miles Teg was present. Arbelough had been perverted by Face Dancers and Teg's aides urged their commander to sterilize the planet but Teg refused to and spared the enemy, apart from the Face Dancers.

Following two days of heavy losses at Arbelough, Teg admitting that he had underestimated the fervour of the opposing force, the Bashar led his troops from the front into battle to show that he shared the same risks they did. Later Teg also walked unarmed through enemy ranks before they laid down their weapons to assure them that they would not be mistreated.
