Seacrest

In a contest among the gods, long and long ago, Shalimyr  challenged Master Korak to make him a blade out of water. This was a task that drove the King of the Crucible to utter distraction, until one day he hit upon the secret: that water holds reflections. So he made a magnificent falchion of the most shining metals and gems, and then caught its reflection in a pool. He bade Shalimyr to take the reflection from the water, and because the water was a part of the Endless, and thereby the reflection, Shalimyr could do so. Holding aloft this great curved blade, Seacrest, the god of the ocean looked upon Korak with gratitude and offered to pay him with a boon. 

Master Korak thought on this a time and could not think of what he would ask of Shalimyr the Endless. He did not ask for anything for many an age, until one day Shalimyr was prepared to flood the many mountain tunnels forged by the hands of dwarves. The Sea Father was infuriated that the stout folk hated the water and did not sail upon it. So Master Korak asked for this boon: that the dwarven people be forgiven forever by Shalimyr for their arrogance. It has allowed the dwarves, more than any other race, to build lasting monuments of stone, and great cities unmarred by erosion and time.

Shalimyr is as good as his word and forgives them the arrogance of believing that anything they build will last. What happened to the original blade, from which the reflection was caught? None can say.
