Being Interrupted during his meditation would normally have been a bit annoying. He and Fleur were making a massive benefit of the runes around them. Their elemental mana storage and conversion in to natural mana was very high in the core of the ship.
However, the reason they were interrupted was that many rune carvers were taking positions around the rune array at the core of the ship. It appeared that they were making the best of what Walker had said earlier. He had unintentionally encouraged them to push themselves to make the rune adjustments and add even more wind elemental runes.
The main reason why Walker was interrupted was that Gil was speaking to the rune carvers. His voice was louder than the carvers since he was trying to get a clear understanding of what he would have to do. "So, you want Zephyr and I to channel the wind down here in the middle of the ship? Is that safe? You know that there is not much moving air down here."
