In both cases, the process revolved around infusing them with a massive amount of Light. A Shadow Priest player helps by draining the Void as well, but unlike Light Naaru falling to the Void when they're drained too much (which fits the theme, since "Void" can also suggest emptiness), there's no precedence to suggest that simply draining a Void object of power will turn it to the Light.
Still, that scene is worth thinking about. Xal'atath was gathering vast amounts of magical energies into the Dark Heart and, if Alleria was correct, converting it to the Void. She tried to drain the Beledar, but we interrupted her and Alleria broke the Dark Heart. So, if she's returning to her plan now that it's fixed... wouldn't her next step be to resume draining the Beledar (as the roadmap implying the Hallowfall story would be in 11.1.5 suggests)?
Perhaps "Nightfall" will be Xal'atath succeeding in her initial goal. Beledar will be fully drained, either making it permanently dark, or just... empty and powerless. And that will give her enough power to move on the Worldcore in 11.2.
