The hot springs were a welcome respite from the cold, but even they're overrun with Svanir and icebrood. I met a quaggan farmer there named Simooba who showed me the hottest spring of all. Its waters flow up from near the heart of Tyria, and they were just what I needed to cook my thaw elixir. I have it now, so I'm ready to breach Jormag's bitter cold.
