All staff, including champions and summoners, were briefly evacuated from the Institute of War today when trace amounts of a synthetic arcane disease were detected in the Luminary Cloister. Adjudicators were alerted to the danger of a foreign presence when magical seals surrounding the Cloister were tripped during off-hours yesterday afternoon. The disease warning has been lifted, and League officials are confident the situation has been contained. They predict returning to “the usual routine” by late tomorrow evening.
