Timothy, the team, and his three-hundred slaves strode the sea, and they all had one goal in mind. They wanted to get to the Ruins of Aqumus, and there, they wanted to reap every ounce of mana that they could get!
Considering how highly the ruins were spoken of, even his slaves could upgrade their mana quality, without meddling in the progress that Timothy and the team wanted to make. There should be plenty of mana to go around, though he swam about twenty meters forward, in front of everyone else, so he'd be the first in line to reap any and all mana quantities!
Tim wanted to be first, because it would be weird if either of his slaves somehow ended up reaching a higher level of mana quality than him! It wouldn't only be weird, but disadvantages too, because he figured that a super-powerful undead guy would want a will of his own, rather than serve a master!
