A pair of gargantuan Mejsterkolm constructed on the mouth of the Turnen des Zee during the height of the Elfenkrijk, the Emerald Towers are a significant cultural icon of the Olskir, and are featured prominently on the flag of the Hesvoline Empire and the Imperial Seal. The towers began construction in PUTC 211 and completed in PUTC 37, at which point they were used to seal Gargat Murk, ending the Elfenkrijk’s war with the Graggrok. The source of the Emerald Towers’ extraordinary power was lost after the Elfenkrijk’s collapse, leaving them unusable monuments to what many consider the height of Olskir civilization.
