no , hals has not been closed off like althar has , for agon , aelor save us , had no reason to close the gates there , nor , indeed , any true way to do so , bar bringing down the caverns of fire beneath the earthbut even that could not be done , for the stone and fire of hals is not a physical thing , and only the dead may travel there ; for such is the ordinance of those who created these worlds , and they are beings beyond being from a time beyond all time , and we speak little of these , the elad ni of the void .
