Summoned to Council by Lindariel  

The Vales of Ered Wethrin

They forded a nameless tributary of Sirion, then turned northwest and followed it upstream into the vales of Ered Wethrin. Though it was nigh midsummer, the weather in the mountains was cool enough that Alatáriel was grateful every evening for her heavy hood and cloak. How the three guides stayed warm enough in only their light, silvery grey cloaks, she had no idea. But they seemed happier now, unexpectedly breaking into song day and night. Thavron grew more friendly, talking shop with Teleporno about the trees in this part of the world and what their wood was suited to become.
