Three days had passed since the moving city started to move towards Snowsaint and a few hours since they arrived at it. The militaries went the conventional route to talk with the Mayor about lifting Kyrie's restrictions, meanwhile, Kyrie and his friends "entered" the city by alternative means.
Kyrie "entered" Snowsaint by the same entrance he did the first time around, or better yet, he sneaked past it with Allen's help, and so did Maremalle. Lily grabbed his back, while Miniraka hid inside his mane of hair for ease of moving around inside the city.
Allen's shadow powers were convenient, they could hide Kyrie and Maremalle within the shadows as if they were in a pocket while Allen lept from shadow to shadow, bringing them deeper within Snowsaint. It was an interesting, and equally powerful ability to have.
It explained how Allen could score kill after kill against the flying termites.
