The next team was led by Luis and Drake, taking the rear areas, and they were still doing their best to get through to the walls.
Although Althea couldn't make System announcements as this wasn't her territory, she could still send them through aether letters. However, she opted not to do so after a few moments of thought, even if it risked winning the war prematurely.
She didn't ask anyone to slow down their pace because she couldn't risk lives just to get the token. In the worst-case scenario, they'd just have to prevent him from gathering strength for revenge by barraging him with wars until they get it.
This was why all three teams were still going strong, barrelling towards the walls as fast as they safely could.
