Mila
Mila waited for the dead of night and then started moving. She'd figured out the camp layout during the day, and she knew where the tents of the leaders were, so she headed to the tent of the general furthest away from Isaiah's, the tent housing Omalia Gale, niece of the Gale Clan leader.
From the conversations she'd overheard, she knew Omalia and the clan leader's twins leading the invasion were not perfectly aligned, so she had an idea on the best way to get the information she'd originally been after when she'd targeted Isaiah.
Disguised as a non-existent relatively young Gale Clan member, she walked up to the two guards in front of Omalia's tent and saluted like she'd seen other Gale Clan members do, placing her right hand over her heart with fingers fully splayed. "News from the Life Tree Empire's forces."
