While the time the two spent together in their quest couldn't be called long, it could be called short either. Around a month according to Noah's estimate.
During that time, they had hunted some monsters to extract certain parts from them, gathered some ore and rare treasures that grew naturally in the Tartus fragment, most of which couldn't be found on the surface world.
Along the way, Aelia had also drawn some magic circles at some intervals. While Noah couldn't tell their function at first, after watching her draw multiple ones he discovered they were all linked together as part of a giant magic circle.
Their journey wasn't an easy one by any means as it tested their perseverance and their limits, with Noah almost losing control of himself on different occasions. Luckily he was able to find the right balance and they carried on.
