Grain remained hidden while the large group made their way into MainVillage.
He wanted to infiltrate at the same time they entered. This would allow him to use the large group as a distraction. If they had to confirm any identification, or be checked for contraband, he would slip in behind the interaction.
Unfortunately, the group was let in within minutes and he had barely made it inside the cities borders.
He was using Darkness to avoid detection but surrounding the city, was multiple layers of platforms carrying armed Merlurks. They had also trimmed the trees to allow sunlight in, severely reducing the effectiveness of his skill.
This was the same reason he was seen before, being slightly exposed from the sunlight peeking through the tops of the trees.
Away from the settlements of the Merlurks, the forest's ceiling was dense and hardly let in any light. It was obvious the creatures had trimmed the overgrown trees used to build their homes.
