The importance of Aetherium for Rowan could not be overstated, for although he had an infinite pool of powerful Primordial Aether in his dimension, Aetherium was the next step for this power, but it was gate-keep by the Primordial forces who used the seeds of Aetherium as a bargaining chip to draw geniuses to their side.
The act of gathering Aetherium from the ocean was two-fold, the first was to give him a potent source of energy as he wondered the sort of power he might be able to wield if he used Aetherium instead of Aether to power them, and the second was to learn how to forge his personal Aetherium using the degraded Aetherium of Doom Star as a guide.
If he could succeed, then his act of rejecting the offer of the Aetherium Seed from Elura would not sting as much, and as a hidden hand he could play, Aetherium would be a very potent weapon.
