Author: Estyrien al'Halien
Halvar was the First of Mayene roughly three hundred years ago. The Tairen fleet was planning to find Mayene's oilfish shoals, the source of Mayene's wealth, and so Halvar tried to appease the High Lords. He raised the price of Mayener lamp oil so that it was more expensive than Tairen oil and gave the High Lords the redstone doorway ter'angreal that had been in Mayene's possession. He had already used it and so the ter'angreal was of no use to him. The Tairen fleets did not find the shoals, but it proved in vain as the High Lords had Halvar assassinated the following year.
