Lex smiled. Although Pel had yet to actually bring about any substantial results, and only seemed ready to pursue its passion spanning multiple lifetimes of searching for treasure, he was already satisfied. After all, anything was better than randomly searching the land.
Given that his spirit sense could span a very large area now, which should technically ease the search somehow, it would still be a great undertaking if done alone. Moreover, he was not so sure spirit sense could find the resin so easily.
After all, if this resin really was the Amber Chaos resin, as Pel claimed, and the Tree of Heaven already tasted some of its benefits, then it is likely that it had been searching the continent for more of it for a long time.
In fact, if things were as Lex expected, and the races living under the tree's canopy were its servants, then this resin may be the reason for some of the wars he had seen from above.
