Elemental cores weren't exactly rare, but as excellent magic materials, they were consumed on a large scale both in enchantment and magic-equipment-forging.
So, not many of them were available on the market.
Besides, it was even harder to gather five kinds of elemental cores at the same time.
Therefore, Roland was rather surprised that the Guild of Mercenaries delivered the five types of elemental cores so quickly.
Meeting with the men from the Guild of Mercenaries and giving them the final payment, he got the five elemental cores.
Roland had read introductions to elemental cores from the books in his Magic Tower. They were said to be rhombic crystals the size of an adult's fist. Different elements would result in different colors.
Those cores were rather beautiful. They seemed to be crystals, but there was flickering magic light flowing in them like very tiny shooting stars.
